I can’t tell you if there have been changes or not on the server but in any case they can’t rollback

Unfortunately no

Yes, all cookies are deleted. I tried from other browsers or in private browsing but I cannot log in. No one else can log in but they have access to the site

I restored a backup before the problem appeared but that did not resolve the problem

I haven’t touched the server but other people have access to it and were able to make changes

I had the same result as when I replaced the site files :
The site pages except for the front page are now returning a 404 error but I still have access to the back office login url and I still cannot log in and I still don’t get an error message

The site pages except for the front page are now returning a 404 error but I still have access to the back office login url and I still cannot log in and I still don’t get an error message :/

Unfortunately no

When I had my old theme (Divi) activated I had the “Cannot modify header information – headers already sent by” error message and also the “cookies are blocked due to unexpected output” error message but when I changed to another theme (I tried with Twenty Twenty-Four and Kadence) I no longer have error message but I still can’t login

Nothing happens, the login page simply reloads, no error message is displayed

Sorry I meant there is no error message and I can’t login

Hello,

I don’t think it’s a theme related issue, I tried with another theme (Kadence) and still can’t login without getting an error message

As I said there is no error message when I use a default wordpress theme :/

I did change the password but nothing change, even when the credentials are correct I have no error message and I can’t login
