WordPress Won't Let Me Log-In to Dashboard

Hey All –

Have never experienced this before, so wanted to present to see if you could help.

Every time I attempt to log-in via my standard /wp-login.php page (I have the correct username and PW), the page automatically goes to my website’s homepage rather than the dashboard. In my 4+ years of running the site, it always automatically logged me in and went to the admin dashboard.

The homepage then gives me the option to “Log-In” or “Register.” Clicking, “Log-In” just brings me back to the page I just logged in from.

Essentially, it’s a circle of log-ins but it’s not actually logging me in.

Any advice? Very frustrated.
