have you created a support ticket with your valid UBB license information? have you updated to the current supported version of ubbt? have you looked at your htaccess files to see if there is anything out of order? have you cleared your forums cache directories? have you run the ubbtest scripts? what steps have you taken to resolve this? what are your server details? among many others, those would be the next steps to take. the use-to-user forums are supported by end users.
you can start an official support ticket with you valid license here:
