We updated the Cornerstone plugin because we were having trouble with saving work while using Cornerstone. While the plugin was updating, I got a message that the plugin update failed and that it has automatically been uninstalled and deleted. Now the pages that we built using cornerstone are not loading and I can’t move forward with building this new site. I need help!
Example page built using Cornerstone: http://xgx.31c.myftpupload.com/apprentice-agents/

Hello. neither of those suggestions worked. On my third attempt, I took a screen shot of the error message that shows up when the Cornerstone plugin attempts to update. And I added that code to the file you suggested and the saving in cornerstone is still delayed. Any other ideas?
