For the Pinegrow for WP plugin:
There are several php warnings that appear. I know I can turn them off, but thought of report them so they get updated in a future version. THere a few more but they all refer to the same class.
Deprecated : Creation of dynamic property Pinegrow_Plugin_Public::$in_dev is deprecated in /var/www/html/public/wp-content/plugins/pinegrow/public/class-pinegrow-plugin-public.php on line 91
