I was planning to upgrade my installs to dnn 7.1.1 from dnn 7.06 but on testing on a local machine I have noticed that the File manager just disappears.
The file manager page exists but the module for the file manager is not in the host extentions.
I have also tried to upgrade in steps..
Upgrade 7.06 to 7.1 then to 7.1.1, the first step worked, the file manager was present in 7.1 and working. Upgrade to 7.1.1 and then the file manager disappears again.
