I used Austin Matzko's WordPress Database Backup plugin to backup my site (www.andyrathbone.com), and all seemed to go well. It created the backup, and I downloaded the backup file to my PC.
But when I visit my site (www.andyrathbone.com), the Home page no longer displays *any* Posts, nor do any of the direct links to the Posts work. Only the Pages appear. All of my posts are still visible from my Dashboard, as well as all the comments. But none appear on my Web site.
Now I'm not sure whether to restore from an older backup -- losing a few posts in the process -- or try to republish all my old posts, as they're visible in the Dashboard.
