I have the guest sign in plugin installed for a few days, and just noticed today they guests trying to login through the form weren't having any luck. I came across this error after attempting to login:

Fatal error: Call to a member function on a non-object in /home/devloung/public_html/forum/extensions/GuestSignIn/default.php on line 70

My default is untouched besides the addition of an image next to the guest welcome title, and a custom signed in message. Any ideas?
