re: to myself and FYI , after the HTTP 500, i resumed access by
1. renaming the themes/buddymatic -> buddymaticXXX
2. /wp-login.php now accessible, logged in -> this redirected to a blank page at site www root
3. opened /wp-admin/ page anyway, and was accessible
4. clicked into /wp-admin/themes.php, a message indicating a corrupted template appears(well in my case in Japanese), message also says it would change back to the default template because of this.
5. root page now appears normal, still looking over for any unusualities..
went through this by blind guesses, not sure if it’s good or not
