All posts vanished!

All of my June posts have disappeared! It happened when I clicked to advance to “June” in the sidebar calendar. Now only the heading and date appear for the most recent post, while everything else is blank! I have tried uninstalling the calendar plug-in and deleting the code from the template, but nothing works. I have even tried republishing each post, but that didn’t work either. It’s been two days now. What’s going on!
