# jQuery broken in WordPress CMS?

 * Hi! I’m cleaning up someone’s WordPress site and I need to edit the widgets… 
   However, something is blocking these simple toggles for expanding/collapsing!
   This includes:
    – the navigation on the right – the toggles on the dashboard.–
   Quick edit won’t toggle. – Categories tabs (All categories/most used under Post)
   won’t toggle – The dropdown on the top right won’t toggle – The screen option
   and help tab on the top right doesn’t toggle. – the Visual/HTML tag DOES toggle.–
   ALSO – there is no more shadow box for the image, media, etc. panels (above the
   WYSIWYG)! It opens as a new page in the same browser.
 * I’ve never encountered this issue before. I’ve reinstalled this website’s wordpress
   a few times, all the plug-ins are up to date, it’s the latest version of wordpress.
 * Could a plug-in effect the back-end? Could something in the front-end theme effect
   this? Which folder should I look in for the .js script for expand/collapse, to
   make sure it’s there?
 * This should not be any different, but just in case: I am using a Mac Book Pro,
   and these issues are coming up on Chrome, Safari and Firefox.
 * Can’t wait to hear everyone’s suggestions and ideas! Thanks. ♡

 * Yes. Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem? If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause
   problems.

 * Hi Esmi. Thanks for your reply. I have not yet done that, setting sometime aside
   for that.
 * If I deactivate a plug in will I lose all my settings for that particular plug
   in?
 * Thanks!

 * If you just deactivate the plugins (as opposed to deleting or un-installing them),
   they _should_ retain their settings.

 * Well, there’s no accounting for badly written plugins, I’m afraid.

 * Not necessarily badly written, just out of date. The previous developer had installed
   this: [http://wordpress.org/extend/plugins/wp-post-thumbnail/](http://wordpress.org/extend/plugins/wp-post-thumbnail/)
 * Thanks so much esmi!
