No need to copy the entire page.... Your error is listed in the main body. Right after the greek.
"Lost connection to MySQL server during query"
The explination for which is "The most common reason for the MySQL server has gone away error is that the server timed out and closed the connection."
I'd suggest restarting mysql and see if that fixes the issue. If you are on a shared server you should submit a trouble ticket so your host can investigate as this is a larger mysql error.
