Custom Tapatalk- vBulletin 574 Integration Fix

I need a skilled developer to reconnect my existing Tapatalk integration with my vBulletin 5.7.4 forum. This is a critical task, as only vBulletin supporting members should have access to Tapatalk.

Requirements:
- Reconnect Tapatalk for vBulletin supporting members only
- Custom error message for non-supporting members: "Access denied: Only supporting members can connect via Tapatalk."

Ideal skills and experience:
- Expertise in vBulletin and Tapatalk integration
- Experience with custom error message implementation
- Strong problem-solving skills

Please ensure that during development, non-supporting members cannot connect via Tapatalk at all.
