That's still not including the actual error message. It's the part below "server error" and above the numbered lines. Alternatively, you can look at the "server error logs" in the admin CP and that should have details.

Unfortunately, this is a server error or a MySQL bug; there is nothing that we can do to prevent it (well, except not using prepared statements). (The MySQL issue is discussed here: )
I'm getting a similar "error" on both my sites.
Is this just a hosting issue, surely there has to be something we can do, I don't think we should consistently see reports in our error log?

i got onto my host and they found this

I noticed that InnoDB was disabled in your /etc/my.cnf.
I've enabled that since your site may need it and restarted MySQL.
and so far its all working.
