Warning: Division by zero in /includes/modules/theme307/featured_products.php

[serovectra]

Upgraded from 1.3.9h to 1.50, Final upgrade does not show items in cart.

I installed the ZenCart update using Dreamweaver FTP, then ran zc_install. PHP Version: 5.2.17 (Zend: 2.2.0). Database: MySQL 5.5.29-log.

The issue started after I did the final update and went live. I tested it perfectly on a copy site, and database, via on how the upgrade instructions informed me.

I have a Theme named 307 as my template, which preformed perfectly on the test site, my log files do give me a:

[29-Jan-2013 11:23:58] PHP Warning: Division by zero in /home2/koonberr/public_html/zen_test/includes/modules/theme307/featured_products.php on line 100

I checked these lines, and have searched around for the error I am getting in site after selecting shopping cart, or adding to shopping cart, which is: TEXT_PRODUCT_NOT_FOUND. This error seems to be coming from code in includes/languages/english/document_general_info.php & product_free_shipping_info.php & product_info.php, as well as others that state:

define('TEXT_PRODUCT_NOT_FOUND', 'Sorry, the product was not found.');

, except strangely the "Sorry, the product was not found" does not display.

I searched around on this forum and http://stackoverflow.com to figure out if it was a php issue on the template, but I could not figure it out.

It eludes me, it worked perfectly, I even redid the installation upgrade on the database, and reinserted the updated files into the proper directories again. I would greatly appreciate any advice that would help me to figure this issue out.

Oy. DW is famous for skipping files when doing mass uploads via its so-called "FTP", and never telling you that it failed to upload half of your files.
I never trust DW for mass uploads. Maybe one file at a time, sure. But never entire directories or subdirectories.

TM templates are very prone to problems especially since they hack apart a lot of the core code and seldom update any of them to correctly work with the latest version of Zen Cart let alone the latest version of PHP.

Sounds like a coding error in their customized file.

Not sure what those files have to do with the featured_products.php module. I suspect they're merely messengers of a deeper problem.

What exactly is different between your test site and your live site? Obviously there are differences or it would be working fine in both instead of only working correctly on the test site. You could be missing important files on the live site, you might have "extra" files on your live site which are interfering with normal operation, you might have different content in the live-site database compared to the content on your test-site database, the two servers might be using different PHP versions, and the list goes on.

Thank you for the quick response, I will go ahead and restart the test site from scratch. I will also use winmerge to see the difference in individual files between the test server, and the live server. I think you may be on key with the fault of DW's FTP, do you have any good recommendations for open source "FTP" programs? I know I could google it, but you seem to be someone who is much more in-tuned, considering you answer 85% of the problems on zen-cart, and apply the information for updates.

I find this list rather helpful: http://www.zen-cart.com/wiki/index.php/Useful_Tools

I redid the entire site again, from scratch, using winSCP to upload the files. I also decided to use the default ZenCart Template, but I still receive the "TEXT_PRODUCT_NOT_FOUND" when I go to the check out, or I check my cart. I'm starting to think it's a database error. Any other ideas?

Sorry, this is the error I am getting now.

If it's literally saying "TEXT_PRODUCT_NOT_FOUND" instead of the defined language string normally used for that, then you're missing language files or part of their content.
