No modules displayed in back office

[whitecandle]

Hi

I purchased the Prestanews Module just now.

I went to the BO and used the 'add module' feature.

Now when I selected Modules Tab it is empty - no modules!

I deleted PS News Module but the problem is still here.

All the modules are in the folder.

I have added the debug 'on' option to config.inc.php but nothing comes up??? or not sure what I should see??

Please advise.

Regards
