I heard that vBulletin's iif function is depricated. This could easily be the cause of the issue, since it may not be defined properly for the use of outside code. However, since it's still being used in forumhome - I don't think this is really the case.
iif is a ternary operator.
variable = iff(boolean, true, false);
is the same as saying
if(boolean)
{
variable = true
{
else
{
variable = false
}
So you might consider replacing the iif calls with the idea above - there aren't many of them.
Next, there's a hook being called. I don't know if you have any calendar affecting plugins, but it might be causing your script to break. You might want to remove the hook.
Areas of code I mentioned are highlighted:
