By default, it seems that Spam Protector expects all upper-case text, however entered as such, the string is not validated.
I remedied this easily enough by modifying the CAPTCHA alpha character array to lower case:
Code: Select all
$this->chars = array_merge($this->chars, array('a','b','c','d','e','f','h','j','k','m','n','p','r','t','u','v','w','x','y','z'));
Thanks,
