Quote by pezastic: You're right, it had nothing to do with the recent GeekLog install - just a coincidence.
Well, since you mentioned cookies - maybe not. It's possible that FileMan and Geeklog use the same cookie names.
If you experience any further problems (with either FileMan or Geeklog) that may be cookie-related, try renaming Geeklog's cookies (in config.php).
