I have a WP.org blog. Wanted to install Jetpack. Logged on to WP.com with Akismet credentials. Went back to WP.org admin pages to install Jetpack. Installation manager recognized my WP.com account (do you want to link "www.X.org" to WP acct XYZ? I said yes, then got a HTTP 500 error. Now I can't access my WP.org admin pages AT ALL. Everytime I access it directly from the browser or from within WP.com, I get the 500 error. I'm using Chrome. Have cleared cache and cookies and restarted. Have tried Firefox and Safari. Nothing. No access. WTF.
Thoughts? How is it I can't access my admin pages???
