undefined function zen_check_url_get_terms() error

[fmcnally]

Ok I've lost my page/site (the site is just Zen Cart)...
The site - www.sassybenz.com/shop - now has this error-"Fatal error: Call to undefined function zen_check_url_get_terms() in /home/content/42/5153542/html/shop/index.php on line 30"

This site has been up and running for the past month just fine. I don't know if it was me or the other person who caused this error. But what had happened is this same "other" person sent me an email with some code that i was suppose to put on the index page (www.sassybenz.com/shop) i did and uploaded...got this (current) message on the site.

I thought I could just delete the JS code, upload again and all would be fine....it's not obviously

I then spent several hours googling for an answer as to why this had happened and how I could fix it. No luck but a lot of rabbit trails.
Ended up calling the web host for tech support and quickly realized they knew about 0 PHP and even less about Zen Cart.

The code below is what the actual code on the page is that is producing this error. If anyone knows what I need to do, please let me know.
Code -

You need to seek the index.php that is at your /shop level
Upload a fresh copy that is from the same version as you are using

Thank you Kobra....Stupid question, how do I get a "fresh copy" as you say?
I mean, I had originally just taken out the copy & pasted code (the JS code that started this mess), gotten rid of all whitespace, and uploaded the page to the server.

I really appreciate your help! This seems like it shouldn't be happening

One more thing-
After repeated attempts of uploading/not working/look at code/upload, i found this ;
phpxref.com/xref/zencart/includes/languages/english/index.php.source.html

and saved it as the index.php page in the /sjop file. Well, of course it didn't work as evidence of the recent site being down....just FYI, that's all (seems like a good site though!)

This sites main page - but you need to know what version you have loaded...
http://www.zen-cart.com/index.php

Don't know what this means???
There ARE NOT "Pages" in a php application that can be likened to a html page/file

Thank you so much---again!...very much appreciated.

The version of Zen Cart is 1.3.8a.1 I found out.

The 2nd "problem" about the page will probably be controlled once Part 1 is finished.
