Hey to remove the notice of YITH plugins you should go to every plugin of YITH you have and edit the file in folder “/plugin-fw/licence/lib/yit-plugin-licence.php”
At that file you should comment out the line that says:
add_action( 'admin_notices', array( $this, 'activate_license_notice' ), 15 );
This means adding // to the front of that line or /* */ on both ends of that line.
it should look like this:
// add_action( 'admin_notices', array( $this, 'activate_license_notice' ), 15 );
or
/* add_action( 'admin_notices', array( $this, 'activate_license_notice' ), 15 ); */
Remember, this must be done on every YITH plugin you have.
