Well, if this is upgrading UBB5, follow the steps carefully. Copy all new CGI files and ALL files located in the VARIABLES folder from the ZIP file into your current UBB CGI directory on your webserver. The variables all begin with "vars_****.cgi". They need to be CHMODed 777. All the new CGI files you just uploaded must be CHMODed 755. In the ZIP file, you see a Members directory, DO NOT upload this over your current Members directory.
PS - You misread the upgrade instructions, it clearly says
If u need me to clarify, feel free to post again.
In essence, you upload EVERYTHING except the Members directory. That means, VARIABLES are included in the upload.
