Worpress – registration and login form does not work

We need a prompt solution to the following problems:

1. The form of registration and login to the site does not work, the site is on a new version of Wordpress, apparently something with the theme.

That is, to the site /registration/
and
website/login/
You need to fix them to work with the current topic.

2. And check the operability of the form site /forgot/ forgot password.

See the attached file for details.

From you the cost and terms are MANDATORY!!!
