I recently notice a whole host of strange issues in the admin areas of my site. I run a multisite network, and these issues are happening across all sites network wide. I have disabled all plugins and tested with the default themes, and I've replace the wordpress files with clean versions, and no joy.
Some of the issues include flyout menus not working, the menu editing interface is missing options, the widget editing interface is broken, some buttons appear very large. Those are the primary things I've noticed.
The front end of sites is fine. Much of the functionality is fine, but I would like to get to the bottom of what could be causing this.
