Greetings all.

I recently took over the administration tasks of a Zen Cart based web store. Although I am new to Zen Cart, I am not new to websites.
The first thing that I did was create backups of the site and its relative databases. After looking through the site's code, I realized that the previous admin had a *lot* of modifications in place that did not seem to come from add-ons or modules(no or minimal commenting and poor formatting). The ones that did originate from modules or add-ons were easily recognized(full commenting and formatted to blend in). So, in an effort to keep the development moving forward, I set up an exact copy of the site in a new directory - complete with it's own (cloned and renamed) database and edited configure files. The backup site works, almost. I have spent many hours looking through the code in an attempt to separate the original, the modules,/add-ons, and my predecessor's code. No, it isn't much fun to do that. The problem I am having is that links still want to point back to the live site and that can not happen for testing and future development. I *think* I tracked the issue down to "zen_href_link". If I am on the right trail, where is this defined? I looked through the code and all the database tables, but I could not find it. I did try to use the developers tools, but the results were not helpful. If I am wrong in my assumption of "zen_href_link" being the issue, does anyone have a suggestion about the way to repair this? I will need to continue to modify the site to fit the owners needs, but I can not do this to a live site. I have to use a test site to accomplish my goals.

Thank you in advance for any help you can provide.
