Hello, I have deactivated all the plugins and it continues to give error 404 in the language admin, could it be because the server is configured with nginx and should be configured as apache?
Mañana lo probaré y te informo si hay avances.
If you do me the favor of checking the site to repair the fault, I will pay you for the time spent.
The problem is that I have backups with duplicator pro but when I restore these copies on a test site, it doesn’t work either so I can’t do tests because I don’t really dare to perform the tests by itself it stops working.
