Dusted off our Demo system yesterday for a demo today and one of the projects wouldn’t load.  
Checked the version and found 7.1.4B? so I upgraded to 7.1.6 and got the same response.

I then restored the last backup and the problem went away.

I have zipped up the wrapper.log and the autobackup files and uploaded them for when you have a slow afternoon 🙂

Thanks - 7.1.4 suffered from some nasty internal database stability problems across restarts. 7.1.6 has proven to be quite stable.

Glad to hear that about 7.1.6. I just upgraded a customer to that last week.
