@Adriano Faria - Ok after a few days here, and @ehren. looking into his themes, this isn't a theme issue. All themes are up-to-date and current. If you click on the +Create drop down and select "Create Invitation" a popup appears allowing you to do so (make an invitation.) The little ticket icon in the user menu bar however takes you to your account settings but with nowhere to input any invitation information. If that popup had some sort of visible URL to it, I could come up with a functional solution however I can't even create a menu item with a URL in the meantime, essentially making this useless right now, which is a big deal for me as this site allows registrations through invitations only.
Also, a majority of my users are on MOBILE devices - The invitation options doesn't even show up. So again, some sort of shortcut that I could use in a menu would be beneficial right now.
Any help you could provide would be huge right now.
Edit: I did not realize there was an update out for this. THIS solved my issue and all is working quite well again.
