I was surprised this morning to hear that the contents on my WP site are erased, said my client. I tried disable all plugins one by one, but the problem still exists. I also changed the memory limit via the wp-config and that could not solve the problem either. Then I switched to another theme, twenty-eleven and twenty-twelve, they all show those missing contents.
This is my first time building a WP site, and I've no idea why it occurs. http://www.dcaredental.com/news-event/tv-interviews/
Any help would be very much appreciated.
