Title: Plugin not PHP backward compatible Last modified: June 2, 2018 --- # Plugin not PHP backward compatible * [Arsie Organo](https://wordpress.org/support/users/eyesfortech/) * (@eyesfortech) * [8 years ago](https://wordpress.org/support/topic/plugin-not-php-backward-compatible/) * This review could have been 5-star ONLY if I was able to install it. However, I just found out that the plugin is not PHP backward compatible. The plugin will cause fatal error if the PHP version is below 5.6. * My hosting PHP version is 5.4.45 and I am unable to use this tool.

You should truly consider upgrading. Your logic for 1-star review is flawed. * [http://php.net/supported-versions.php](http://php.net/supported-versions.php) - This reply was modified 8 years ago by [TT74](https://wordpress.org/support/users/tt74/).

Not only to use our plugin but to also ensure your site overall is secure. * Security is very important to us and we do not want to jeopardize this by supporting outdated PHP versions. * Hopefully, once you have updated your PHP settings and are able to install the plugin you can give us another review based on your experience. * Thanks! * Plugin Author [Fernando Claussen](https://wordpress.org/support/users/fclaussen/) * (@fclaussen) * [8 years ago](https://wordpress.org/support/topic/plugin-not-php-backward-compatible/#post-10362031) * PHP is now in version 7.2. I’m supporting version 5.6 and up. How’s that not backward compatible? I even state the plugin requirements before you download it and block users from activating it so they don’t get frustrated about the plugin not working properly. * It’s not really my fault that your host is using an ancient version of PHP. * Moderator [Jan Dembowski](https://wordpress.org/support/users/jdembowski/) * (@jdembowski) * Forum Moderator and Brute Squad * [8 years ago](https://wordpress.org/support/topic/plugin-not-php-backward-compatible/#post-10363181) * _*Reads. Removes `modlook` tag.*_ * I’m leaving this review in place. I’m pretty sure this feedback is accurate even if I think it’s a bit silly to leave a review like this. * Here’s why. * > The plugin will cause fatal error if the PHP version is below 5.6. > My hosting PHP version is 5.4.45 and I am unable to use this tool. * This plugin also does not work in Ancient Sumerian or other dead languages. Don’t use this or other modern supported plugins written in a version of a language that is not riddled with security vulnerabilities and has no support from PHP. * Yes, WordPress itself works on PHP 5.2.4. * [https://wordpress.org/about/requirements/](https://wordpress.org/about/requirements/) * But that page starts with this. * > To run WordPress we recommend your host supports: - [PHP](http://www.php.net/) version 7.2 or greater. - [MySQL](https://www.mysql.com/) version 5.6 or greater OR MariaDB version 10.0 or greater. - [HTTPS](https://wordpress.org/news/2016/12/moving-toward-ssl/) support * And it shortly says this too. * > Note: If you are in a legacy environment where you only have older PHP or > MySQL versions, WordPress also works with PHP 5.2.4+ and MySQL 5.0+, but these > versions have reached official End Of Life and as such **may expose your site > to security vulnerabilities.** * If your host doesn’t offer a supported version of PHP then they either don’t care about their users or they don’t like them very much. You really need to find a responsible host provider. * [Joseph G.](https://wordpress.org/support/users/dunhakdis/) * (@dunhakdis) * [7 years, 11 months ago](https://wordpress.org/support/topic/plugin-not-php-backward-compatible/#post-10434823) * An awesome plugin gets a nice 1 star review because it does not support PHP 5.4.
