 * Hi [@rcharbonxx](https://wordpress.org/support/users/rcharbonxx/),
 * First off, I just want to say that I’m not affiliated with WP Super Cache, but
   have been using it for many years, and am a huge fan of this plugin. (Also, a
   fellow plugin developer.)
 * That’s a false positive. See [this thread](https://wordpress.org/support/topic/false-positive-showing-wp-super-cache-as-not-php-7-compatible/),
   as it’s already been reported to the PHP Compatibility Checker plugin devs.
 * Unfortunately the PHP Compatibility Checker plugin is not too accurate. It uses
   a flawed detection method. All it ends up doing is creating a headache for other
   plugin developers. (We’ve been through this a few times with our plugins getting
   falsely flagged as well.) If you look at its 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 in logging-only mode. (See instructions in
   our [WordPress Debugging Guide](https://www.redsandmarketing.com/wordpress-guides/debugging/?wpdg=wp_debug#wpdg_wp_debug)
   if you need any help with this.)
 * I hope this info helps!
