no access to wp-login.php

Hi,

I have just changed a domain name for an old hosting.
First problem, the past old WPtheme was erased.

Second big problem :
I no longer have access to WP admin of this new domain because of this transfer.

At the connection on the website, it sends me back to the wp-login.php of the old domain name, same thing when I access the lostpassword loss, it remains blocked on the old domain.

In summary the new domain with the old hosting dont match with my email, my user name and my password.

The consequence is : i can’t update a new version and then i acn fix the first problem.

I thank you for your help !!!!
