Some errors are occurring with the Classic Editor after updating to WordPress 5.5. I can type text in the Visual editor, but I’m unable to select the Text editor tab. There is no response when I click on the Text tab.
I can add URL links but I cannot edit them. I can click on the link and click Edit the first time, but I cannot select “Link options” as that only disables the main scrollbar in the Chrome browser. After the scrollbar has been disabled, the Edit option for the link is no longer available.
The following JavaScript errors are returned in the Chrome browser console:
