UBB.threads is not currently compatible with PHP8, however UBB.threads v7.7+should be able to run on the latest PHP7 without issue.

We do not advertise PHP8 capability anywhere on this site, and the product won't be completely migrated until all core assets have been fully updated to support it.

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.
