I had this happen yesterday,took me down for a few minutes.But it had something to do with the izap plugin.It was the same fatal error message.Would this be the same as the error you are talking about?

Would I take your code and replace the code at the top of your post?

I'm sorry I cannot assist you in relation to the plugin (since I don't use if of course). I am just explaining what worked for me, it may or may not work for you but there is a high probability that the cause it the same. The solution above only works if you have the exact same setup (i.e. no extra plugins + external database connection). Anything else is beyond my scope.
