I recently updated my WordPress through GoDaddy. Ever since I did, I can't log in to my dashboard. Everything on the site functions properly, but when I type in my username and password, I'm relocated to a "404 missing" page. On the admin dropdown, no matter what I click on, I'm directed to the same "404" page. I can't access the dashboard, themes, plugins...nothing. I have tried renaming my plugin folder to deactivate them with no luck. Any thoughts?
