# Multiple WP Interface Errors After 5.5 Upgrade

 * I have two separate installations of WordPress (on the same server, with some
   plugins in common and others not) and have been experiencing widespread interface
   issues since the WP 5.5 upgrade. These seem to be focused primarily around form
   fields and buttons, including media uploads.
 * All of these issues are specific to the /wp-admin back end.
 * – The main text editor is entirely nerfed. I use the Text editor, and now the
   entire toolbar is gone and I cannot switch to the Visual editor.
 * – Media uploads are nerfed. The “Add Media” button does nothing. Rather than 
   opening the upload overlay, “Set featured image” navigates the entire browser
   page to [my-site.com]/wp-admin/media-upload.php?post_id=31833&type=image&TB_iframe
   =1. This interface is also non-functional for uploading images (“Select Files”
   does nothing).
 * – Tags require a click of the “Add” button to add. The Enter key no longer adds
   typed tags, but rather saves the page (while the cursor is in the tags field).
   The browser also no longer suggests existing tags.
 * – Sub-menus do not pop out when mousing down the main WP menu on the left-hand
   side. If I click a menu option, its submenu will briefly appear before the page
   changes.
 * – The bulk select-all tickbox at the top of pages (e.g., Posts, Plugins, plugins
   ready to update) doesn’t work. The box will toggle ticked, but nothing below 
   it on the page will.
 * – The “CMS Tree Page View” plugin no longer displays the page tree, but only “
   Loading tree.”
 * Thanks in advance for any help.

 * Update:
 * Installing the “Enable jQuery Migrate Helper” plugin has resolved all of these
   issues. (Read the plugin’s description to understand why. Prior to WP 5.5 this
   was apparently included in the core.)
 * In my case it was an outdated version of the Magic Fields plugin that was throwing
   deprecated jQuery errors, which impacts things all across the admin back-end.
 * (I’ve also learned through this that Magic Fields no longer releases updates 
   through the WordPress plugin library! Yikes. Off to download the latest version
   of that plugin …)
