A login redirect loop sends you back to the login page even with the right password, usually from mismatched address settings or confused cookies.
What it means
You enter your correct username and password, click Log In, and get bounced right back to the login page. It's not a wrong password - something is redirecting the login process in circles.
Why it happens
The usual cause is mismatched WordPress/Site URL settings (http vs https, www vs non-www) confusing the auth cookies. Security plugins and certain caching setups can also cause it.
What to do
- Check Settings > General - WordPress Address and Site Address must match exactly (including http/https and www).
- Clear all cookies for your domain in the browser.
- Clear server and CDN caches - cached redirect responses cause loops.
- Temporarily disable security plugins - they sometimes interfere with login redirects.
- Check .htaccess for redirect rules that might catch wp-login.php.
Still stuck? Login loops are usually a URL mismatch - quick to fix once identified. We can trace the redirect chain and correct it.
