I tried to invite some people using fInvites. I got the following error message:
Please set your owner e-mail first at fSettings section.
I typed in my email at fSettings and I got the activation email. I clicked on the link in the activation email. The page I was redirected to loaded and stayed white with no confiramtion. When I checked, the owner email address was still N/A. I tried it again with the same results.
