Fatal error: SUHOSIN - Use of eval is forbidden by configuration in /home/w******/********.com/piwi/libs/HTML/QuickForm/Renderer/ArraySmarty.php(268) : eval()'d code on line 268
(In [2296]) quick fixes #1421 - add Installation check requiring eval() ... used by HTML QuickForm and Smarty
oops, forgot eval() is a language construct. function_exists('eval') always returns false ...
(In [2299]) fixes #1421
(In [2300]) fixes #1421 - but for simplicity, it doesn't check suhosin.executor.eval.whitelist or suhosin.executor.eval.blacklist
