I have installed agama on a new site, but the registration failed (www.markdeklusser.be).
I went to check on an older site I have, where the registration was already successful (www.equisource.eu).
When I pressed submit again and this also failed.
I have quite a few site using Agama Pro, as I was told you can use it on as many sites as you like?
We have released a new version of the Vision Core Plugin.
Please go to the plugins section and update this plugin(the latest version is 1.2.3)
And try to theme register by using order id and your email.
