Hi. When i try to insert on "Custom php.ini settings" a value with ^ , for example PHP: error_reporting = E_ALL ^ E_STRICT i get an "Invalid php.ini settings" error. The ispconfig version is 3.0.5.4p1 The old 3.0.5.3 version not had this issue I think that the problem is in the fix Code: Fixed FS#3320 - Improve php.ini parser where in the latest regular expression not consider the ^ character.... There is i problem if i change this regular expression from the actual PHP: if(preg_match('@^\s*;*\s*[a-zA-Z0-9._]*\s*=\s*[-a-zA-Z0-9~&=_\@/,.#\s]*\s*;*\s*$@', $custom_php_ini_settings_line)) continue; to PHP: if(preg_match('@^\s*;*\s*[a-zA-Z0-9._]*\s*=\s*[-a-zA-Z0-9~&=_\@/,.#\^\s]*\s*;*\s*$@', $custom_php_ini_settings_line)) continue; ? Thanks
