🔐Login Keeps Redirecting Back to the Login Page

Why this happens

After a successful login, WordPress sets an authentication cookie and redirects you back to wp-admin - but if your site's URL settings don't match your actual domain, a security plugin blocks the cookie, or the cookie domain is misconfigured, WordPress can't recognize that you're logged in and sends you back to the login screen in a loop.

Step-by-step fix

1. Clear your browser cookies and try again, or use an incognito/private window.
2. In phpMyAdmin, check the wp_options table - siteurl and home should both match.
3. If a security plugin (like Wordfence) is installed, temporarily disable it by renaming its plugin folder.
4. You can also try manually setting the cookie domain in wp-config.php if the issue continues.

How to prevent it happening again

• Keep your WordPress Address and Site Address settings consistent and matching your actual domain.
• If using a security plugin, check its login protection settings after any major update.
• Avoid running two security plugins that both manage login attempts, as they can conflict.
