The login was correct, it’s just that I kept getting a 404 page. Thank you for your assistance. I just decided to delete the plugin and update the URL manually via .php.
This is happening to me as well, and I bookmarked my login and put it in my notes app, so I know it’s correct. No matter what, it keeps showing a 404 page. Now I am locked out of my own site and the developer FAQs on what to do if you’re locked out are horribly written and confusing. How do I regain access to my site?
