In this tutorial we will show you how to fix the Joomla 2.5 javascript error that occurs when using the Module Manager. This may occur after performing an upgrade, and the error will look similar to this:

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete."

This error typically occurs when you have a large number of menus, and the javascript times out while processing them. This can be solved by replacing the validate.js file with a corrected version.

We are assuming you are familiar with your website's file location, here is a link to an article that explains the directory structure in deeper detail

Fix the Javascript Error:

  1. Backup your Joomla website.
  2. Using FTP or File manager navigate to the existing validate.js file located here:
  3. Rename the existing validate.js something like:
  4. Download the corrected validate.js file from github.
    Here is a link to the full download page:
  5. Extract the downloaded file and upload to:
  6. Now, clear your browser cache, then log back into the Joomla! Admin panel.


Congratulaions, now you know how to fix the issue with Joomla 2.5 that causes javascript errors when using the Module Manager! We would like to thank the Official Joomla Support forum for providing this solution.

I have used the fix and it works well, however, when I have the fixed validate.js installed, I have issues saving the global configuration and saving users.

If I replace the fixed validate.js with the original, global config and users work and the module saving is slow again, Sigh!

Hello Glenn,

I'm sorry to hear that you're having problems with the validate.js file. This is an issue with Joomla 2.5 for which we unfortunately cannot fix directly for you. The developers who work with Joomla would need to provide a fix as John Paul indicates above. The best link I've found detailing their efforts to fix the issue can be found here. This fix addresses module manager issues. As Joomla is above version 3.1, you may find that updating to the latest code might be the only way permanently fix the problem. If you do update, make sure that you backup your website files and database.
