It's a PHPMyAdmin screen so it'd be UBBThreads 6.5.5

I still do my v6 upgrades as v7.0.0 -> v7.2 -> Latest; once v8 is out it'd be v7.0.0 -> v7.2 -> v7.5.x -> v8

I am a Web Development Contractor, I do not work for UBBCentral. I have provided free User to User Support since the beginning of these support forums.
