Hello,
Yesterday I configured a server running on nginx, php8.1-fpm, and mysql57. Unfortunately, I am having a rather unusual problem with logging into the Admin CP panel. Logging into the forum works perfectly fine, but logging into the Admin CP is causing issues. When I try to access the Admin CP through the AdminCP button after logging into the forum, sometimes I am redirected to the AdminCP and I am logged in right away. My URL then looks like this: domain.com/admin and I am logged in. However, sometimes I get a window where I have to enter login credentials. I enter the correct login details and only the URL changes. At first, it looks like this: domain.com/admin/?app=core&module=system&controller=login&ref= and when I enter the correct credentials and click login, it changes to admin/?app=core&module=system&controller=login&error=&ref= and I am unable to log in. There is no message or error, only the page refreshes and &error=&ref= is added to the URL. This doesn't always happen, sometimes I am logged in right away, and sometimes the login window appears, causing this issue.
If I log out of the AdminCP after being redirected and logged in right away, I am unable to log in again, and the above problem occurs once again.
I would greatly appreciate any assistance. Thank you.
