I've tried posting this on the Umbraco forums to no avail. Hoping to find some help here.
I thought I upgraded successfully from 4.0.4.2 to 4.5.2 (on my way to 4.8...) as I received no errors and everything seemed to go smoothly. However, in the backoffice, when I click on any section other than Content, I get redirected back to Content. I can manually reach each section by typing in the name of it after the # sign like: #media, but as soon as I click on a tree item, it redirects me back to Content. Any ideas would be appreciated.
