If you mean custom menus, you may try another browser.I understand some people have trouble with drag and drop in Chrome. Also make sure java is enabled in ie or firefox.. Also try deactivatiing any other plugins which may use Jquery.
I updated to the latest wordpress and no
issues, yet.
I just tried IE and I got this message: HTTP 500 Internal servererror…?
I also tried to create a new menu, but it will only let me ad one item in the menu. I haven’t added any plugins recently, but it is not long time ago that I did changes on the menu. I do not remember if I did the changes before or after the update though…
I tried to deactivate all plugins and it worked!!
