Replace in include/common.php:

function hex2bin ($input, $assume_safe=true)
   {
    if ($assume_safe !== true && ! ((strlen($input)%2) == 0 || preg_match ('/^[0-9a-f]+$/i', $input)))
          return '';
      return pack('H*', $input);
   }

With:

if(!function_exists("hex2bin"))
{
    function hex2bin ($input, $assume_safe=true)
    {
        if ($assume_safe !== true && ! ((strlen($input)%2) == 0 || preg_match ('/^[0-9a-f]+$/i', $input)))
            return '';
        return pack('H*', $input);
    }
}
