When you moved the UBB, did you follow the backup and transfer guide? If you followed the guide, you shouldn't need to update vars_config.cgi.
I suspect the following is the problem:
6. From the Backup/Variables directory on your local machine, upload ALL files *EXCEPT FOR vars_config.cgi*. DO NOT OVERWRITE vars_config.cgi UNDER ANY CIRCUMSTANCES.
You probably want to verify your Variables path in vars_config.cgi to be sure it is set to the correct path. I visited your site, and it looks like your UBB is in /cgi-bin not /cgi-local
