Issue: BB code [SIGPIC][/SIGPIC] showing on "About Me" page instead of signature

Hello everyone,

I noticed that on rou's and Grrrr's "About Me" page I can't see their signature, only the BB code [SIGPIC][/SIGPIC]

http://aarinfantasy.com/forum/members/rou/
http://aarinfantasy.com/forum/members/grrrr/

and yet deso's page shows her signature

I've had this problem in Firefox, Chrome, Iexplore and Safari.

Edit: I've asked another member about this and he has the same problem, noticed it a while ago (could be a few weeks).
