I just moved all of my sites over to Spry last weekend, and I'm having some errors that I didn't have on my previous host.

The most troublesome only apprears periodically and it looks as if all the variables from my search are dropped.

When this occurs, I'm given the error: "Notice: Undefined index:......"

I asked a few of my other programmers, and the said it's most likely a server issue, not a PHP code issue. Is this correct? Can anyone assist?
