Everything was running fine and I didn't touch any files or SQL tables, when I logged in to the Dashboard and discovered:
1. The normal space for "WordPress Development Blog" and "Other WordPress News" is now empty. (But everything else is there.)
2. When I post, edit a page or post a comment, a blank page loads after pressing the "Save" or "Post" equivalent buttons. However, the pages are saved, posts and comments are made safely.
3. Under Manage >> Posts, my posts are not loading. However, my pages load fine.
Lastly, everything on the site front is loading fine.
Is this just an SQL glitch that will go away with time? I have another WP powered blog installed on a subdomain and everything seems to be fine there.
Any clues? =(
