I’m stuck in a login redirect loop and can’t reach wp-admin, can you fix it?

Yes. A login redirect loop (or ERR_TOO_MANY_REDIRECTS at wp-admin) usually comes from a mismatched siteurl/home setting, a stale cookie domain, an .htaccess rule, or an over-zealous security plugin. We fix it through wp-cli and direct database edits, no need for the broken admin to be reachable, and restore your access in minutes.
