I have just accessed the site it is OK

I cannot access it since I still dont receive the invitation code in my gmail.
Is gmail blocking the email code?

I don't think so; I am also using gmail.

Site appears fine for me.

Not good still not receiving verification code. Not even the backup code work.
The email support not working also.
i did email but no reply.

The discrod invite link also not working.

Anywhere else can contact them?

This is not the right place to ask for support issues related to the B4A forum.
I see little point in you making repeated posts here when you are getting authoritative solutions.

You should probably contact the person who provided you the invitation code in the first place. That should solve your issue.

Here is notice from B4A frontpage:

Backup codes and discord should work. It's always better to use an autthenticator app (ms, google, authy) instead using email for 2fa.

The forum too hot using anything like phone can trace back to me.

Not going to be the last one getting caught for doing a silly move.

The gmail sending problem still not fix saw the notice at login screen.

Backup codes dont work and as for discord I never apply for one until this problem crop up.
