Issues with WordPress 5.3

Hi,

I’m testing your plugin on my test environment and it seems there’s a plugin conflict with s2member and WP 5.3 when trying to create group types. After creating I received the following errors on screen:

Warning: sprintf(): Too few arguments in /wp-content/plugins/s2member-pro/src/includes/syscon.inc.php on line 100

It would be great to take a look into compatibility with WP 5.3 – thank you.

Kindest regards ??
