If there's an error log file there, it's configured to work that way. AFIK, it can't be "turned on" or "turned off", but rather is a result of the PHP installation in the server itself. Even then, it may be automatically "on" no matter what, I'm not sure, to be honest. In any case, that would be under the control of the sysop/company managing your server.
If there's no log entry since 2005 for that folder, that should mean either that there have been no actual PHP errors by any PHP code *residing in that folder* since 2005, or that there have been no error because the code is not actually being used.No need to apologize. I'm kinda/sorta semi-fluent in PHP, but certainly no guru in it either. My problem is I'll go a couple of years in between major coding projects and I'll have to remember things and blow cobwebs out of my head all over again every time
