How to fix: err_response_headers_multiple_location error in Google Chrome

The "err_response_headers_multiple_location" error in Google Chrome typically occurs when the server sends multiple Location headers in the HTTP response, which is against the HTTP specification. To resolve this error, you can try the following steps:

1. Refresh the Page: Sometimes, simply refreshing the page can resolve temporary issues. Press F5 or click the refresh button in your browser.
2. Clear Browser Cache and Cookies: Clearing your browser's cache and cookies can resolve issues caused by outdated or corrupted data. To do this in Chrome, go to Settings > Privacy and security > Clear browsing data, choose the appropriate time range, select "Cookies and other site data" and "Cached images and files," and then click "Clear data."
3. Disable Extensions: Some browser extensions can interfere with how websites are loaded. Try disabling all extensions and then re-enable them one by one to identify if a specific extension is causing the error. To manage extensions, go to chrome://extensions/ and toggle off the extensions.
4. Check Server Configuration: If you have control over the server, review the server configuration to ensure it is not sending multiple Location headers. This might involve checking your server's configuration files, such as Apache’s .htaccess or Nginx’s configuration files, to make sure there are no conflicting redirect rules.
5. Use a Different Browser: If the problem persists, try accessing the website using a different browser to determine if the issue is specific to Chrome.
6. Update Chrome: Ensure you're using the latest version of Chrome, as updates often include fixes for bugs and errors. Go to Settings > About Chrome to check for and install any available updates.
7. Contact Website Administrator: If none of the above steps work, the issue might be on the server side. Contact the website administrator or the support team of the website you are trying to access and report the error.

What causes the err_response_headers_multiple_location error in Google Chrome?

The "err_response_headers_multiple_location" error in Google Chrome is triggered when the server sends multiple Location headers in its HTTP response. This violates the HTTP specification, which dictates that only one Location header should be present in a response. Common causes include:

• Server Misconfiguration: The most common reason is a misconfiguration in the server's redirect rules. For instance, multiple .htaccess files on Apache servers might contain conflicting redirect directives, leading to multiple Location headers being sent.
• Conflicting Redirect Rules: If a website has multiple redirect rules that apply to the same URL, the server might erroneously send multiple Location headers in an attempt to process all the rules.
• Third-party Plugins or Modules: Server-side plugins or modules, especially those that handle redirects, can sometimes introduce errors that result in multiple Location headers being sent.
• Load Balancers or Proxies: If the traffic goes through load balancers or proxies, they might add their own Location headers, which can result in the error if not properly configured.

Can clearing the browser cache resolve the err_response_headers_multiple_location error?

Clearing the browser cache can sometimes resolve the "err_response_headers_multiple_location" error, but it is not a guaranteed solution. The effectiveness of this approach depends on the root cause of the error. Here’s how it can help:

• Outdated or Corrupted Cache: If the error is caused by outdated or corrupted cache data, clearing the cache can resolve it by forcing the browser to fetch fresh data from the server.
• Temporary Glitches: Sometimes, clearing the cache can resolve temporary glitches that might cause the browser to misinterpret server responses.

However, if the error is due to server-side issues such as misconfigured redirect rules or conflicting server settings, clearing the browser cache will not resolve the problem. In such cases, you will need to address the server configuration or contact the website administrator for further assistance.

Are there specific Chrome extensions that might trigger the err_response_headers_multiple_location error?

While no specific Chrome extensions are universally known to trigger the "err_response_headers_multiple_location" error, certain types of extensions could potentially cause this issue. Extensions that manipulate HTTP headers or redirect traffic might inadvertently cause the server to send multiple Location headers. Here are some examples:

• HTTP Header Modifiers: Extensions that alter or add HTTP headers, such as "ModHeader" or "Requestly," could potentially cause conflicts with server responses, leading to multiple Location headers.
• Redirect or URL Manipulation Extensions: Tools like "Redirector" or "Linkclump" that modify URLs or redirect them can interfere with server-side redirect logic and cause the error.
• Ad Blockers and Privacy Extensions: Some aggressive ad blockers or privacy-focused extensions like "uBlock Origin" or "Privacy Badger" can modify how requests are handled, which might result in unexpected behavior from the server.

To identify if an extension is causing the error, you can disable all extensions and then enable them one by one to see if the error reoccurs. You can manage your extensions by going to chrome://extensions/ and toggling off the extensions to test.
