The error "MySQL server has gone away" is most probably caused either by a crashed table or by a heavy SQL query which takes too long to execute and as a result the mysql server times out.

If you have recently enabled any new mods, I would advise you to disable them and see if this helps. You can also contact your host and ask them to investigate the issue.

@D1m0
thank you i will go in and disable my mods and see if that helps out. I also just noticed that my mysql version is MySQL 5.0.91 according to the ACP, but in the error and in my template above is indicated 4.0... let me know if that would cause any errors.
If you have a moment could you also see my post below and let me know if you have any ideas on that one or maybe these two are related?

That means nothing.

Please disable your mods one by one and see if it helps to alleviate the error.
