In my opinion it is indeed the protector module. Disable it and you wil see the uploaded modules. I am not sure but when I had this problem I think I did it by set the module protector of in de database. It is a few weeks ago i cannot remember. Good luck.
I think it has something to do with a require. A function has allready been required. I think you must find dat require and change it in: require_once() And see what hapens. The_mouse
In your case its something else. I think the best you can do now is post it on the site of wf-downloads http://smartfactory.ca/modules/newbb/viewforum.php?forum=12
I think it is one of the modules you use that takes to much memory. Have you instaled a new one? Maybe you can deinstall that module and look what is going to happen. Succes, de_muis
