The text input where the Groups section can be located and added to the User’s Profile on the User Edit screen is only 10px wide, and it doesn’t function. I’ve also looked at the source code of my page and it’s pulling the selectize script and CSS from jsdelivr and there’s no indication it’s being pulled in from the Groups plugin. It’s possible that there’s a plugin or function conflict, but I’m not pulling that in on anything I can see from my code or the plugins. The functionality of ADDING the User to a group works fine from the purchase side of my WooCommerce site and my functions.php code, but manually adding the User to a Group does not function.
