I have a problem with the upgrade from chevereto free 1.0.9 to latest 1.0.10 Everything is working fine, but if i upgrade to 1.0.10 every time i restart the browser and go to my-domain.de/chevereto...
^^^ That file was not included in 1.0.10 and caused the issue.
The issue in 1.0.10 didn't included MySQL gone away neither proxy proxy_fcgi:error. Like I said, I doubt is related (also I don't get a 500 but an empty 200).
On load the software does hundred of instructions, any of these could be failing or issuing another sub-system to fail like MySQL. With the information you have provided I'm afraid that the problem is not in the software but your server setup. Otherwise it will happen on every load not just sometimes.
You should try checking the MySQL tables and issue the REPAIR TABLE statement for the tables that may look odd.
