Hello, I have the site offline because during the upgrade to version 4.7.9 the procedure stopped indicating error 500.
Can you help me to resume the upgrade
Thanks for the help

It looks like you may have restored, but you should be able to find more information about what caused the 500 ISE in the servers PHP log. 

I do note that you have a lot of error logs from the last few days indicating MySQL server issues including a lack of disk space.
