I installed the update and have since experienced a plethora of problems that prevent me from running/maintaning my site properly. I have also encouraged my clients to avoid the update for the time being as a result of these issues.
The first is that I can no longer add links using the visual text editor, and the previous HTML editor (now renamed "text") cannot even be accessed. I click on "text" and nothing happens.
I also cannot do anything within the Widget page. Literally, anything. I can't expand any of the sidebars to view included widgets. I can't even drag anything around. Useless.
Anyone else having these problems/know a fix? If not, I'd rather just roll back to a previous version when these things worked.
