OK, just being stupid. For anyone trying to track down the key that is giving the Disallowed Key Chars error, just temporarily edit your input class on line 215ish:
Code:
function _clean_input_keys($str)
{
if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))
{
echo $str;
exit('Disallowed Key Characters.');
}
return $str;
}
Then you actually get to SEE the error, which in my case was a dollar sign, and not the square brackets!
