I think people are going to need a bit more info in order to be able to help you here.

-What URL are you trying to access that’s now blank? /wp-admin/ ?
-Did any cpanel / apache / etc. updates happen on the server overnight? Maybe an update to a required library failed.
-Does your hosting provider have backups? You could restore in the worst case scenario.
-Please define “everything” from the limited info above it sounds like you can get to the editor – do you mean the post editer – therefor the control panel and other parts are working fine and you just can’t edit a post using the WYSIWYG editor? Or do you mean the whole control panel is gone and /wp-admin/ is a blank page?

From the above post it looks like everything’s fine. Perhaps Google just hasn’t picked up the redirection yet.

You could check your .htaccess file as Platinum SEO likely created a rule there. You could delete that rule but then if you do any search engines or inbound links to your new URL (……diamond-for-a-loved-one/) will then fail. And I’d say that 404 would be worse than a duplicate content warning.

Alternatively, you could change the redirect to go the other way and redirect “…..diamond-for-a-loved-one/” –> “…..diamond-for-a-loved-on/” that should cover both scenarios.
