Hi Freddy!
Forum is working on Discuz! 7.2.
TP can not log and throw an error.
You wrote that the added support of the question,
but a new version of the problem is not corrected.

Can anyone help?

You don't need to enter any answer here on logging in.

This working for me fine. Maybe you have chosen bad type (it's "Discuz") or entered bad id.

Yes, it's my fault.
Strange, but it was the wrong password.
Everything works fine.
Thank you for your support!
