 * Hello
 * Thank you for a great plugin! When I run PHP Compatibility Checker to check my
   plugins for compatibility with PHP 7, I get the following error and warning:-
 * FILE: /home/myaccount/public_html/wp-content/plugins/rs-system-diagnostic/includes/
   admin.output-data.php
    ————————————————————————————————————— FOUND 1 ERROR AND
   1 WARNING AFFECTING 2 LINES ————————————————————————————————————— 44 | ERROR 
   | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – 
   use mysqli instead. 95 | WARNING | INI directive ‘safe_mode’ is deprecated since
   PHP 5.3 and removed since PHP 5.4. —————————————————————————————————————
 * Is this something that needs to be addressed?
 * Thanks and regards

 * Hi [@janaa](https://wordpress.org/support/users/janaa/),
 * > Thank you for a great plugin!
 * You’re welcome!
 * _The plugin is fully PHP 7 compatible._ Unfortunately the PHP Compatibility Checker
   plugin is grossly inaccurate. It uses a flawed detection method. All it ends 
   up doing is creating a headache for other plugin developers. If you look at it’s
   support threads, you’ll see it’s full of false positive reports. In our tests
   of over 100+ plugins, it’s had false positives in the range of 30-40% (depending
   on the version).
 * The way to accurately test PHP 7 compatibility is to run plugins on a test site
   on a PHP 7 system and use WP_DEBUG. (See instructions in our [WordPress Debugging Guide](https://www.redsandmarketing.com/wordpress-guides/debugging/?wpdg=wp_debug#wpdg_wp_debug).)
 * I hope this info helps!
 * If you have any further questions/issues, please see the [sticky post](https://wordpress.org/support/topic/please-read-before-posting-updated-feb-2017-6/)
   at the top of the forum for support info, and we’ll be happy to help.
