I have a blog through my Yahoo Merchant Store that is run by WordPress. I login through a WordPress interface, my dashboard is all WordPress.
Yesterday, I attempted to install a plugin from the WordPress site and believe I may have put the code in the wrong place. Everything just went blank. I couldn't go back to undo it. I couldn't get into the dashboard. The site is all blank.
I spent over two hours on the phone with Yahoo's technical support yesterday, manually restoring screenshots back to June 25. Yahoo reps don't know anything about WordPress and can't help me and WordPress doesn't seem to recognize my blog as one of theirs.
