How to fix
“Application error: a client-side exception has occurred” on Chrome
on Windows

How can I fix this error: "Application error: a client-side exception has occurred (see the browser console for more information)"? I get this on some pages. They seem to be loading at first, but then they become black with the message at the middle. What can I do here?

Sometimes, users of Google Chrome may get the error message "Application error: a client-side exception has occurred." It usually shows up when there is an issue with a web application that is operating within the browser. It can happen in a number of situations, including when a webpage loads, when using web-based interfaces, or when in-browser applications that heavily rely on client-side scripts like JavaScript are being executed.

The root causes of the "Application error: a client-side exception has occurred" are often related to issues within the web application itself, such as buggy or incompatible JavaScript code, conflicts between the web app and browser extensions, or corrupted browser cache and cookies that disrupt normal app behavior. In addition, corrupted cache files or cookies may also result in you not being able to reach certain websites.

Users who encounter this problem may notice that it affects their browsing experience, resulting in web pages that fail to load properly or interactive functions that do not respond as intended. It can be especially bothersome when it happens frequently or when attempting to do important things online.

For those not comfortable with manually tinkering with browser settings or code, using a [d1] repair tool might be a practical solution. These tools are designed to automate the troubleshooting process, efficiently identifying and fixing common browser issues without the need for in-depth technical knowledge.

Fix 1. Clear browser cache and cookies
