I have just recently updated to 3.5 but these problems were issues before I updated. Things that are not working are:
• The "Edit" permalink button - nothing happens
• The "Preview Changes" button when you're working on a page - it doesn't update the page with your changes
• There used to be a bar at the top of the page when you were looking at your site that included a button for edit this page. That bar is completely gone. There's space for it, it's just not there.
• In the Contact Form 7 plug in the "Add New" button - nothing happens
• The MP3-jPlayer plug in - doesn't show files
I am at a complete loss as to why all these things just recently stopped working. It was about 3 weeks ago. I tried deactivating all plug ins but nothing changed.
