If I want all regular users (outside of moderators and administrators) to have the same custom title how do I do that? I want them all to have the same title, regardless of post count.

I removed all of the custom titles in CP and just have one titled "Member" with Min. posts set at 0.

At the bottom, I check the box for:

But, I get this error when I try to update:

UPDATE ubbt_USER_PROFILE SET USER_TITLE = 'Member' WHERE

Hmm, it might be a bit of a bug in the code. It might need at least 2 titles. I'd add a second one being the same title with a different post count and see if that fixes it.

Bingo Rick. Having at least 2 titles did the trick. Thank you.
