Site breaks links after move

[Sramota]

So we moved from Blood-Bowl.se to Alvsvenskan.se
All was fine, just lost old posts swedish letters that all became "?" but meh,
it's no problem.

What IS a problem though is this:
I post a link like this
http://alvsvenskan.se/index.php?topic=216.0
and when I post it, it becomes
http://alvsvenskitopic=216.0/

See the problem here?
What can I do?
I first thought it might be in the repair_settings.php. Nothing there
Then maybe the theme, but both the custom and the standard default has this issue...

Hupp, fixed, apparently using censors with a * in it caused the issue..
