WordPress Upgrade Causing Admin Issues

Recently after the latest round of updates to several client sites, we noticed that we started seeing a bunch of weird wp-admin issues. Some issues occurred in the widget section where we couldn’t move or edit widgets and others happened in the WYSIWYG section of the post editor, where the “link” button wouldn’t popup.

After some Firebug debugging, we saw that we were getting some very random Javascript errors. Since the code was minified it really did not help us at all, but it showed that the “load-scripts.php” file was loading JS files and those combined files were causing some sort of Jquery issue.

We disabled every plugin in the system but still saw issues cropping up.

We jumped onto FTP and compared the files in the server “wp-includes/js/jquery” folder and our own backups (always..backup..before..upgrading). Comparing the live version versus our own, it looked like the jquery.js file went from version 1.11.0 to 1.11.1.

On a whim, we reverted back to the 1.11.0 version and everything started working perfectly again.

Moral of the story, always make a backup of your site prior to upgrading (or set it to automatically backup).

The latest version of WP Admin seems to have issues with the latest version of JQUERY as well.
