Check the browser console

The first step is to open the developer tools in your web browser and navigate to the "Console" tab. Look for any error messages or stack traces related to the application error. The information provided here can give you insights into the specific problem that occurred.

Refresh the page

A simple page refresh might do the trick. Sometimes, a temporary glitch can trigger the error message. Give it a try and see if the error disappears. If it persists, let's move on to the next steps.

Clear cache and cookies

Clearing your browser's cache and cookies can resolve various issues, including client-side errors. Access your browser's settings, find the options to clear cache and cookies, and proceed with clearing them. Afterward, restart your browser and try accessing the application again.

Disable browser extensions

Certain browser extensions or add-ons can interfere with web applications, causing errors. Temporarily disable any extensions that might be causing conflicts and try again. This step can help pinpoint if a particular extension is responsible for the issue.

Try a different browser

If the error persists, it's worth attempting to access the application using a different web browser. This can help determine if the issue is specific to your browser or a more general problem. If the error doesn't occur on another browser, it indicates that you may need to troubleshoot or reinstall your original browser.

Contact the application support

If none of the above steps resolve the issue, it's time to reach out to the application's support team or the website's administrator. Provide them with detailed information about the error message, any relevant data from the browser console, and the troubleshooting steps you've already taken. They will be better equipped to assist you further in diagnosing and resolving the problem.

Remember to document the application you encountered the error in, the steps you took before encountering the error, and any specific error messages displayed in the browser console. This information will help the support team or administrator understand and address the issue more effectively.

Hopefully, these troubleshooting steps will help you overcome the "Application error: a client-side exception has occurred" message and get back to using the web application seamlessly.
