Thank you Abe1. PHP is upgraded and the hack is working now. It generates this
Code:
Warning: arsort() expects parameter 1 to be array, null given in /includes/class_bbcode.php(149) : eval()'d code on line 77
Warning: Invalid argument supplied for foreach() in /includes/class_bbcode.php(149) : eval()'d code on line 79
when the report post function, or some mod functions are used.
