Even your suggestion didn't fix the problem. Here is what I did to find the issue. In the core CI code in system/libraries is a file called input.php I made a small modification to that file so that it would show the actual data in question. Around line number 199 function _clean_input_keys($str) { if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str)) { exit('Disallowed Key Characters: '.$str); // Added the variable to display. } return $str; } I certainly hope this helps others.

Around line number 199

function _clean_input_keys($str)
{
if ( ! preg_match(“/^[a-z0-9:_\/-]+$/i”, $str))
{
exit(‘Disallowed Key Characters: ‘.$str); // Added the variable to display.
}

return $str;
}

I certainly hope this helps others.
