After playing around with Flock and using it to post to my blog, I get the following database error from within the admin screen to write posts under the "custom fields" area:
WordPress database error: [Got error 12 from table handler]
SELECT meta_key FROM wp_postmeta GROUP BY meta_key ORDER BY meta_id DESC LIMIT 10
Now when I post to my blog, I get similar errors when I load my site.
Anyone know what I did to break my blog?
