For what reason did you stop logging into the admin panel?

Question

CMS

Site on a manual engine. Not mine. The problem arose not after some changes in the site, but somehow by itself. On the login page in the admin panel, I enter my login and password, I press the login - the page is simply updated and nothing happens. Previously worked. If you enter the wrong username and password, an error occurs. What could be the reason? help pliz

Often, if authorization stops working for no apparent reason, it means that the disk has run out of space and the session cannot be recorded.

Answer 2

you need to look at the console for errors, and then the Apache logs
