DivaVocals,

Thank you for responding, and I apologize if I did not provide enough information; I try to protect my clients' privacy unless it is really necessary in order to solve a problem,

Honestly I used to feel the same way.. However, it's a website.. There's not much to protect someone from when it can be found in a search engine.. Nevertheless, this is why I build a development site and post that URL here.. If I HAVE to post a client's actual URL, there's way's to make sure it doesn't get "found" by search engine spiders. For example:
http://www(dot)mealsforfunerals(dot)com

and I was hoping someone would recognize the error. The site in question is:

http://www.mealsforfunerals.com

Not likely.. too many factors affect ones store especially when working blindly (we can see your source files) with a vague uncommon issue..

No other modules have been installed, it is just basic Zen Cart 1.50 with a fairly heavily modified template. I only found it necessary to merge one file to avoid overwriting my own modifications:

includes/templates/theme298/common/tpl_header.php

I have double checked this file and the rest of my installation against the instructions in the install.txt file and it appears that I did it correctly to the best of my knowledge. If you need to ask more questions to help solve this issue, please let me know.

Well this will certainly allow folks to weigh in if they have suggestions/solutions to offer..

Also regarding the part I bolded.. Does this mean you did not merge other template/override files??
