Hello @shmanich
Thanks for taking the time to update the ticket.
Just to be clear, v3 works well on our plugin. Actually our plugin is the only plugin to have v3 to v2 automatic fail-over. The issue is as mentioned in our email thread; your AJAX based login/registration is not compatible with the ‘v3 + V2 Checkbox fallback’ setup, which itself uses AJAX.
In the support thread we did recommend switching off the fallback method and it would have worked just as the current plugin you are using does, however you chose not to try it and decided to use another plugin.
Regardless, in light of this I have opened an issue on our plugins development log to check the plugin’s functionality using ‘Login with AJAX’ as well as to see if there is anything we can do to improve support and if it would be possible for it to work with the ‘fallback’ system our plugin can offer.
All the best with your website. Should you have any other questions, please do not hesitate to ask.
Have a great day.
