Suddenly the file manager stopped working in one of my portals.

7.1.2
When I go to the file manager (host or admin) the filelist shows a bunch of files with no names and I cant click any of the folders on the left.

I tried to changce skin and frame to aphelia to ensure my skin wasn't the issue and it didn't change anything.

Also i read that popups had to be enabled, so i checked and it was enabled.

Finally i just decided to upgrade it to the latest v. (7.2.0) and the problem is still there, only now instead of the filelist being a list of no files, i get the round update-icon spinning there and nothing ever happens.

As i did install a news article module from Ventrian, i tried to install the same module on my own website (7.2.0) but my filemanager still works like a charm.

I have another client running on a 7.1.2 and the filemanager there works fine as well.

Any ideas on how to fix this?!?
