I recently upgraded to myBB 1.8.7

Now when I try to change some users groups I get this error:

The style you selected is invalid. Please select a valid style.

I thought "Okay, the style for the groups username is incorrect" but it's not?? I tried to switch a user from one group to another group with the exact same username style and still got the error.

Whats going on? Am I doing something wrong?

What do you mean "when I try to change some users groups", what exactly you are doing when this error appeares?
