Many users attempting to join my forum will come across the Confirmation code. When they get to this, when they properly fill it out, Case sentitive, it will claim it wasn't filled out correctly. I attempted this myself several times. It worked sometimes, but other times it did not work. Is there any way that this can be fixed, or is it that there is something incorrectly being done for this to occur? Thanks in advance.
