User complain about not being able to register on my site, I am clueless...

Hey there,

referring to an earlier thread I already had this topic when I thought it would affect my webview app of the site only. But meanwhile I got reports about users trying to register with their desktop pc and not being able to register.

I could not reproduce this error since it is working for me without any problems. But meanwhile I got proves of registration emails of the users they got though they are not registered in my backend.

So the problem is, they register, get an email of that registration but can not login because the account was not created. My last user who got this problem was or is on Windows 10 with Firefox and I got no clue what is going wrong.

I am running a women only community so I do not want to say anything bad about women but in this case they are not very technophile and can not tell me what they do in details.

Is there anything inside the settings that I maybe screwed up or is there any related bug known perhaps? I have spent lots of cash for marketing and now recognizing lots of people could not register maybe means a big loss.

I have put my login details below but please be aware the site is live and running. When making tests please take care!
