Can you share your full log to pastebin?

When the server restarted all it mentioned was that there was an unhandled exception. I'm not expert enough to read that stack trace to find the root cause.

Honestly, there is a lot wrong in your log. Like finding a needle in a haystack. There is definitely some sort of permission or configuration issue with your config/cache directory. Not sure which. Both?
