I've had a WordPress site since March 2016 but a few years ago I lost the ability to log into my own website. I'm using the twentysixteen theme so there's a little panel at the bottom of the screen that I can click on and log in.
When I do this, the log in window appears, I put my info into the fields and then sign in but get kicked right back to my website and logged out. If I add "wp-login.php" at the end of it, then it sends me to wp-admin but if I now go to my website I'm still logged out.
This is super annoying and I really want to try and fix it, so if anyone has any idea what the heck is going on, I'd really appreciate it!
