I'm in the server cpanel and am looking at all of the folders and files inside the webim folder. The webim folder is set to 755 and the install is set to 644.
Where are you looking that you see an empty folder? I'd like to look at that.
*Updated reply:
I uploaded again and set the permissions to 755 and 644. Now that odd link on the page no longer shows up but then neither does anything else.
