Weird wp-login.php page!

If it’s so urgent why didn’t you include a link to see what’s going on.

I’ve edited my post:

I was able to login to my WP account until today when I cou’d get the correct wp-login.php page. Instead, “PX1” appeared on the page and I couldn’t login.

The URL is: https://www.ruien.uni.cc/wp-login.php?redirect_to=%2Fwp-admin%2F

Please help! It’s urgent!

what did u do to fix this issue? im having the same thing! ??
