Comment on Shield – A Powerful WordPress Security Plugin by Fellow.
Last your update crashed whole my website and it was in such state over than an hour, until I checked it.
Fatal error: Call to undefined method RecursiveDirectoryIterator::setFlags() in …/wp-content/plugins/wp-simple-firewall/src/common/icwp-wpfilesystem.php on line 113
In last update You used PHP class method which is not supported on my PHP 5.2.17 version web hosting server, while I an unable currently to switch to newer version. Method: setflags (http://php.net/manual/en/filesystemiterator.setflags.php ) introduced since PHP 5.3.0 version. You should add PHP version check (http://php.net/manual/en/function.phpversion.php ) to your module to at least 5.3.0. So I think is time to say good bye.
