I have been through all of the above and still am not able to access the visual editor in the following browsers:
Firefox 9.0.1
Google Chrome 16.0.912.77
Internet Explorer 9.0.8112.16421
Safari 5.1.2
I have checked on a Windows 7 machine and a MacBook Pro, both don’t display the visual editor.
I have followed ALL of the above and have even rebooted the router but nothing is working. Surely there must be a fix out there somewhere if this is such a known issue?!
