• You can avoid the confirm form resubmission page with the help of some caching best practices. 

If you’ve been using Google Chrome for a while, you’ve likely encountered several errors while browsing the web. One of the more common and frustrating errors you’ve seen is the err_cache_miss page that displays a confirm form resubmission message. 

Getting the err_cache_miss page means that the page you’re on failed to load cached data. The error can occur for a few reasons, such as: 

• Missing data 
• Network connection conflicts 
• Corrupted cache files 

Luckily, it’s not a complicated issue to fix. You can usually fix an err_cache_miss page by conducting basic troubleshooting like: 

• Refreshing the page 
• Clearing your browser cache 
• Turning off your browser extensions 
• Updating your browser 
• Opening the affected page in incognito mode 

But if you want to eliminate err_cache_miss from your browsing experience, we can help you out. Here, we’ll thoroughly explain the error, provide a detailed repair guide, and how to avoid encountering an err_cache_miss page in the future. 

What is err_cache_miss 

How Google Chrome displays an err_cache_miss page. 

When you see the confirm form resubmission page, your Google Chrome program has a browser cache conflict with the site you’re visiting. However, unlike what its name implies, the page isn’t an actual error. Instead, it’s a warning feature built into Google Chrome. 

The error indicates that the page might duplicate information into a web form. For example, if you visit a website you’ve previously logged in to, an err_cache_miss error will display if you haven’t visited the page after an extended duration. An err_cache_miss page might also appear if you revisit a dormant tab where you’ve used a website’s search function. 

But that’s just one reason for encountering an err_cache_miss page. Other reasons for experiencing the err_cache_miss page include: 

• Browser cache issues. Browsers store information in the cache to speed up page loading. An err_cache_miss error will occur if your cache has outdated data — replaced images or edited text, for example. 
• Network misconfiguration. Google Chrome’s network settings can conflict with a webpage. When information such as DNS (domain name system) settings or proxy servers are incompatible, the browser will display an err_cache_miss page. 
• Website developer errors. An incorrect website caching strategy can affect the browsing experience. A developer changing server resources but forgetting to update the page version can prompt a confirm form resubmission page for the visitors. 

But the err_cache_miss page isn’t a Google Chrome-exclusive problem. Other browsers won’t display the same error page, but they indicate the same issue.

Fixes for err_cache_miss 

An err_cache_miss error is easy to fix. However, there is no single solution for it. Different factors can cause your Google Chrome to display a confirm form resubmission page. Here are five fixes that can address an err_cache_miss. 

Refresh Google Chrome 

Sometimes, a minor glitch can make your browser display a confirm form resubmission page. For instance, if your internet drops for a second while loading a page. In this case, you’ve got a simple solution ahead. Just reload the page. 

There are four ways to refresh a webpage. 

1. Click the circular arrow icon on the top left of the page. Wait for the website to reload and display the page you’re visiting. (Insert image highlighting the reload page on Chrome) 
2. While the browser is your active window, hit the CTRL + R on Windows or Command + R on Mac key combination on your keyboard. 
3. Press the F5 button on the keyboard while Google Chrome is the active program. 
4. Right-click on the web page displaying the confirm form resubmission error. In the context window, select reload from the options menu.

Reloading the page allows your browser to retrieve a new copy of the web page’s data, addressing any issues encountered when it first tried to load the page. 

Clearing the Google Chrome cache and cookies 

Clearing the Google Chrome cache and cookies can remove corrupted and outdated data from your browser’s history and resolve any conflict it might have with the affected page’s server. Here’s why it works. 

• Clearing the cache 
  • The cache speeds up website loading by storing images and scripts locally.  
  • If the stored data conflicts with the existing website, it creates an err_cache_miss conflict. 
  • Clearing the cache deletes the outdated or corrupted resources, forcing the browser to retrieve new resources. 
• Deleting cookies 
  • Cookies are user-specific data like login information. 
  • Expired or outdated logins can clash with the server-side information, producing the err_cache_miss error. 
  • Deleting old cookies makes the browser “forget” logins, removing the conflict with the website server. 

Clearing cookies and the browser cache is a simple process on Google Chrome. Here’s what you need to do. 

1. Click the three dots icon on the upper right section of Google Chrome. 

The Google Chrome settings button, located in the top right. 

2. Select the Settings option. 
3. Choose the Privacy and security option in the Settings bar of the new page.

4. Pick the Delete browsing data selection. 
5. Tick the boxes for Cookies and other site data and Cached images and files. 
6. Click the Delete data button.

After deleting the Google Chrome cookies and cache, the website will reload and correctly display the page. 

Disabling extensions and incognito mode on Google Chrome 

Extensions like uBlock Origin come with user-friendly features like blocking ads. However, these extensions might conflict with some websites you visit. When these conflicts occur, the website will return an err_cache_miss page. 

You have two ways to address the issue easily. 

1. Disable the extensions 
   1. Click the three dots icon on Google Chrome. 
   2. Select the Extensions option and choose Manage Extensions. 
   3. Press the Toggle button on each installed extension so that the toggle is on the left. 
2. Use incognito mode 
   1. Click the three dots icon of Google Chrome. 
   2. Pick the New Incognito window option. 
   3. Type the website you want to visit in the new window. 

Incognito mode opens a new instance of Google Chrome with disabled and fresh settings, cache, cookies, and extensions, eliminating any confirm form resubmission page errors. 

Update Google Chrome 

Running the latest version of Google Chrome enables your browser to run with the latest software, bug fixes, optimizations, and enhancements. Updates help Chrome resolve caching issues, network handling, and compatibility with the newest web standards. An up-to-date version of Chrome can help avoid the everyday conflicts that cause err_cache_miss errors. 

You can get yourself equipped with the latest version of Google Chrome with a few simple steps: 

1. Select the three dots button on the upper right section of a Google Chrome page. 
2. Choose the Help option. 
3. Navigate to the About Chrome section. 
4. Click Check for updates. 

Once Chrome completes its update, the browser will close and automatically relaunch. Then, you can visit the website that returned the err_cache_miss issue, and the update should resolve the error. 

Reset Google Chrome browser settings 

Your Google Chrome’s network settings can cause conflicts with a website’s server, causing the err_cache_miss issue. A settings reset will revamp five settings that can cause browsing issues: 

• Cache settings 
  • Cache size and control settings can interfere with how a website handles resource caching. 
• Extensions 
  • A browser settings reset can automatically remove or disable extensions that create conflicts that result in confirm page resubmission errors. 
• Network settings 
  • Custom DNS or proxy settings can create conflicts with a website, resulting in an err_cache_miss error. 
• Clear cache and cookies 
  • Google Chrome’s settings reset automatically removes deeply embedded caches and cookies that a browser history deletion might miss. 
• Browser configuration 
  • Your browser’s internal settings might become corrupted from failed updates or misconfiguration. A factory reset clears any corrupt files from your browser. 

Resetting your Chrome browser settings is a simple process you can complete in a few steps: 

1. Click the three dots icon on Google Chrome. 
2. Navigate to the Reset settings option on the right side of the new page. 
3. Select the Restore settings to their original defaults option. 
4. Press the Reset settings button in the prompt window that opens. 

Once complete, you’ll have a browser with fresh settings, and the page affected by the err_cache_miss error should be accessible. 

Advanced err_cache_miss fixes for developers 

The following fixes require technical know-how but provide a more permanent solution to addressing the err_cache_miss error. 

Google Chrome DevTool debugging 

Using Google DevTools allows you to inspect the page to see how it interacts with the cache and identify potential issues. The DevTools can inspect network activity, resources, and cache data to find the causes of the error. Here’s what you need to do to use DevTools on Google Chrome. 

1. Right-click on the page displaying the err_cache_miss error. 
2. Click the Inspect option in the context menu. 
3. Select the Network option on the upper right section of the screen. 
4. Click the Disable Cache option. 
5. Refresh the page. 

If you can access the website after the page refreshes, a cached data error is the likely culprit behind the err_cache_miss page. After, you can freely browse the affected web page, you can re-enable the cache by unchecking the Disable Cache feature. 

Flush Google Chrome DNS cache 

Chrome stores DNS lookup files of all your previously visited sites. These files help Chrome improve loading speeds by compressing and accessing website resource data. Occasionally, DNS files can become outdated or corrupt, leading to err_cache_miss errors for sites you previously had no issues visiting. 

You can flush the Chrome DNS cache by following these steps: 

1. Type chrome://net-internals/#dns on Chrome’s URL bar. 
2. Click the Clear host cache button on the following page, which is called the net internal settings page. 
3. Restart your computer. 

Google Chrome will reset to its default network settings after flushing Chrome’s DNS cache and restarting your computer. Once completed, you can access the websites giving you err_cache_miss issues caused by DNS caching. 

Best practices for avoiding err_cache_miss errors 

Getting the confirm form resubmission page can be frustrating. Some fixes are easy to address, but some need a fair amount of time and even require restarting your device.  

You can employ a few tricks and tips to avoid the issue in the future: 

• Update regularly. Keeping Chrome up to date provides the latest fixes and optimizations to help avoid any browser errors. 
• Keep a schedule for clearing cache and cookies. Scheduling periodic cache and cookie clearing for your Google Chrome can avoid caching issues. 
• Adjusting Chrome’s cache settings. Changing your browser’s cache settings can help reduce err_cache_miss issues. For example, you can set Chrome to clear your cache after closing. 

On the developer side, if your site visitors are encountering err_cache_miss issues from your site, you can tweak website settings to help avoid errors: 

• Set cache-control headers. Configure your server’s cache-control headers to handle static resources like images, JavaScript, and CSS (cascading style sheets). 
• Cache-Control: public, max-age=31536000 for long-lived static resources (1 year). 
• Cache-Control: no-cache, no-store, must-revalidate for sensitive data or resources that your site shouldn’t cache. 
• Limit no-store and no-cache settings. Use these settings only for sensitive data your site shouldn’t store on its server. Using no-cache settings on each resource can cause browsers to re-fetch data from every visit and potentially cause err_cache_miss issues. 
• Monitor redirects. Limit page redirects for necessary cases like wildcard subdomains. Pages causing too many redirects can trigger err_cache_miss errors. You can check out our blog on subdomains to learn more about how they affect your page structure. 
• Use Chrome DevTools for debugging. Monitor the Networking tab of DevTools to test if your caching strategy is working as expected. 
• Monitor cache behavior. Tools like Google Analytics, Lighthouse, and WebPageTest can help keep an eye on your site’s cache and avoid potential errors. 

Eliminate err_cache_miss through due diligence 

Getting that confirm form resubmission page can be annoying if you encounter it on the regular. But fixing the issue is a breeze if you know how to deal with it. 

Keeping Google Chrome updated and regular cache clearing are easy fixes to avoid the issue altogether. On the web developer end, it might be a bigger issue, but following our suggested fixes can help your site avoid any caching issues.
