Member profile page crashing?

[AquilaTempestas]

So today I made a few changes (no plugins though. Just slight changes like changing colours of member groups, deleting some threads etc)

and now I have this error when viewing specific member's profile: It's made my forum unusable because this is a top posting member.

OutOfRangeException:  (0)

#9 {main}

All other member profiles are fine. I don't understand?

When changing groups colors, you have many groups in which you have not put the close span class. (</span>)
