uncaught exception: Permission denied to get property Window.App
I got this after upgrading my MovableType installation every time I tried to add/edit a template or entry. The problem was with the domain I was using not being the same as the one set in mt/mt-config.cgi
For example, in mt/mt-config.cgi I had
CGIPath http://robbiebow.co.uk/mt/
But I was accessing the control panel at
http://www.robbiebow.co.uk/mt/
Changing one to be the same as the other and the problem was solved.
