After changing the domain, it is impossible to enter the MODx Revo admin panel, how to fix it?

Question

MODX

The site on MODx Revo worked on a test domain, for example. test.example.com, now tied it to a permanent address - sitename.com. That is, only the domain has changed, the files themselves have not moved anywhere.
Before changing the domain, I cleared the cache and exited the admin panel.
After changing the domain, the pages open, everything is displayed correctly, including the sitename.com/manager admin login page.
But after trying to login, an error page is shown - The resource /manager not found on this server.
I manually cleaned the /core/cache folder, it does not help. How to deal with this problem? Thanks in advance!

Answer 1

Are the MODX configs corrected correctly?
webserver configs?
There are no forgotten redirects, .htaccess files (in case of apache).
What's in the MODX logs?
In the browser console logs?

Answer 2

Somewhere something is left, search in the database / files at test.example.com/example.com
Or, most likely, the absolute paths are somewhere old, also search
