I have a site that's accessible by invitation only. When I send out invites, users can't register from a mobile device. They're immediately greeted by a login page -which they can't use, because they haven't registered. The majority of my users will be accessing my site from mobile devices, so it's paramount that I find a fix for this. I've searched for a solution to this, but I haven't been able to find one. I'm very new to running a community site & very new to Oxwall. Does anyone have any helpful suggestions?
