Error: Undefined index: _fb in fb_get_fbu()
I'm new to Drupal and trying the learn by doing approach, which isn't working very well!
Anyway I got the Like button to work but now it's stopped working and I'm pretty sure I didn't change anything.
When I log in I get this notice:
Notice: Undefined index: _fb in fb_get_fbu() (line 827 of /home/hcomp/tomnod.com/sites/all/modules/fb/fb.module).
Any ideas on what happened and/or how to fix this?
