ATTN WEBSITE OWNERS: If you run a WordPress website, be aware that the latest version (5.5) has some serious issues. Apparently there is a deprecated jQuery function that breaks a wide variety of plugins and even basic editing functions…

WordPress 5.5 update breaking Plugins & Sites, leaving site owners frustrated! Here’s the fix!
After installing WordPress version 5.5, many bloggers and website owners have been reporting problems with the number of plugins installed in their CMS, prominently Classic Editor and Yoast, which happens to be among the most-installed WordPress plugins worldwide. Many website owners have vented their frustration with WordPress version 5.5 on official forums.
The update essentially left the WP admin panel broken for a significant number of website owners. Following the installation, pull-downs and pop-ups would stop working, as also experienced by TheWindowsClub authors. Apart from Yoast, the update also ended up breaking the Classic WordPress Editor plugin for us.
