Space in between username and comma

[Saskia]

I'm having a slight problem which I can't seem to solve on my own, so I hope someone can.

All around my forum, I get a space in between a username and a comma, seperating multiple usernames. It's at the bottom of the forumhome in the "who's online" bit and at the top of forumdisplay where it's stating the moderators and the users browsing that forum.

I'm running vBulletin 3.5.2 and made a lot of template changes to make my forum look like vBulletin 2, but even the unchanged stylesets are having this problem. I hope someone can help me with this.

Thank you.
