Admin Login not possible, input fields blank after submit

Hi together,

i installed YOURLS (1.7.9 & sleeky theme) a while ago and used it whitout problems.
Today i tried to access the Admin area and can’t login:

entered username
entered password
clicked login

After this instead of logging in the login page appears again with empty username and password fields.

I’ve given a new password in config.php but the behaviour didn’t change.
There is no error message when turning on debug mode.

Has anyone expected a similar issue?

best eragrds


Like always : “it used to work and suddenly doesn’t” = “someone has changed something, you just need to find what and fix it or revert it”

Disable plugins (sleeky etc) and test.
