I solved my particular problem by deactivating all plugins and that brought back the posts. I’m reactivating plugins one at a time to find the one that caused the problem. I guess my general question is: plugins are supposed to be compatible. What could cause this?
I have the same problem (http://salesperformance.the-straight-line.com). After updating some graphics and refreshing the page, all the post content disappeared. From the manage tab I can see the posts and tried saving the first one to see if it would reappear, but no. Could sure use some help on this.
I upgraded my account from free to paid and that solved the problem. Thanks for the direction.
I am having the exact same issue with my site http://the-straight-line.com. And it is very frustrating.
