Mysql Unknown Command Error:

Hi, I have a New website jokes.randhawaworld.com but i am hacing severe mysql errors and that are related to:

Error Executing Database Query.
Communication link failure: Unknown command

I ceated a Support Ticket and They said they enabled the Robust Exception handling to dig around. I checked and my queries were causing trouble, i changed the values of some queries to hardcore it they worked but when they were made dynamic it generated error. Slowly all my queries were getting errors. May be my 1 query could be wrong not all.

Can anyone please tell what is going wrong with Me.
