Thanks for your response. I can' get to the files right now as the site was moved to another server with an older version of php.
We are there temporarily as that server will be upgraded soon. Last time I checked I think we are running 2.1.1 or 2.1.2. Most of the files are dated in 2009.
I have made several modifications and patches over the years. I may need some advice on protecting or recreating these when we upgrade. Any suggestions would be helpful to prepare for this.
Thanks as always for your help.
