With a few exceptions, function calls are not permitted in template conditional expressions. Please go back and re-write this expression.

The following functions are allowed in template conditional expressions:
in_array() is_array() is_numeric() isset() empty() defined() array() can_moderate() can_moderate_calendar() exec_switch_bg()


is there maybe a place in vb that i am supposed to define what functions are allowed to be called?
what is happening is when i input that code into my header, and click submit and reload, i get that error and it asks me to return to my header editor, with the new code allready taken out.

is_member_of is a default function O.o
