 * Well, that’s normal, I would check with plugin developers and if it’s false positives–
   update manually using the PHP Version Manager in cPanel or if there’s a problem
   with a plugin – update to its latest version or stay at older PHP version if 
   that plugin can’t work with 7.1 and is imperative for your functionality.

 * Hello [@nikmayo](https://wordpress.org/support/users/nikmayo/)
 * [WPMU DEV Dashboard plugin](https://premium.wpmudev.org/project/wpmu-dev-dashboard/)
   contains some functions for backwards compatibility, that’s why PHP checkers 
   are displaying some errors. Rest assure though, that’s fully compatible with 
   PHP 7.x.
 * Additionally, as this plugin isn’t part of the plugins repository here in wp.
   org, if you’re having any issues with it, do reach us in our support page here:
   
   [https://premium.wpmudev.org/hub/support/#get-support](https://premium.wpmudev.org/hub/support/#get-support)
