Ok, I have worked it out I think. I was trying it while still logged in on my main account and when I tested against a dummy account that I had invited, I got the email but when I go to accept I got the message. It was because I was still logged in on the account sending the invite. You need to log out then sign back in to the dummy account then accept and it goes through.
Ok, got that sorted by adding a new page for members. What I am getting now is a message to say that friendship requests “There was a problem accepting that request. Please try again.”
