When I go to any page that I want to change in the admin area, the page is loading constantly. This is only happening on the pages/posts and not on any other admin areas.
If I deactivate TinyMCE it does not occur. I've cleared cache. As far as I can make out the plugin is working fine (once I found where the styles had moved to!) and the styles are being added ok.
I'm using WordPress 3.9.1 and TinyMCE Advanced 4.0.2
Any ideas why?
