Error when customer inputs "$5.00" in "Apply Amount" for Gift Certificate

jadebox — Fri, 05 Jun 2026 15:06:25 GMT

ZC v. 2.2.2

A customer entered a dollar sign in front of the amount in the "Apply Amount" field for a gift certificate during checkout. This produced an error in the payment module:

Uncaught TypeError: number_format(): Argument #1 ($num) must be of type float, string given in .../includes/modules/order_total/ot_gv.php

I did a hack fix, but hope someone more knowledgeable about how inputs are handled can fix it the right way.

v157 inode limit reached. OK to delete myDEBUG .log files in store/logs?

Peace Freak — Sun, 31 May 2026 16:37:53 GMT

My hosting company has notified me that my store has exceeded its inode limit.

Is it OK to delete all the .log files in store/logs?

If yes, should I leave a few of the most recent ones for reference?

Thanks in advance!

v210 Site is not sending email out to customers.

TamyA — Sat, 23 May 2026 18:33:39 GMT

Greatings all,

Zen cart 2.1.0
Bootstrap 3.7.8

I recently moved the site to a new host and i noticed that when i update an order no email is sent out to the customer, even though email is checked, also when sending email to customers with abandoned carts. I get an error says:

ERROR: Failed sending email to: "customer name" with subject: "Order Update #26470" SMTP Error: The following recipients failed: customer######################:
Please turn on SMTP Authentication in your mail client. ms.srv107.hosting_company.com (www.my domain.com) [Server IP Address]:41382 is not permitted to relay
through this server without authentication.

I also get:
Success: Order has been successfully updated.
Email sent to customer

A copy of the updated order is recieved in the email address using the domain.

I suspect it is a server problem since the email configurations was never changed.
Any thoughts would be appreciated.

v210 V210 V222 Advance search FATAL MySQL error 1055 field not in GROUP BY

OldNGrey — Fri, 22 May 2026 04:12:28 GMT

ZC v222 ZC v210
PHP 8.4.16; MySQL 11.8.5-MariaDB-ubu2404; Template: Bootstrap4 3.7.10 (all templates)

Logfile error (and displayed on screen) is in code block below.

Just place any value in the "Price To" field.

Problem comes from includes/classes/class.search.php.
A quick bodge around line 246 to store the select fields

Code:

$select_new_str =  $select_column_list .

            " p.products_sort_order, m.manufacturers_id, p.products_id, pd.products_name,

            p.products_price, p.products_tax_class_id, p.products_price_sorter,

            p.products_qty_box_status, p.master_categories_id, p.product_is_call ";

and a similar one around line 410 to replace

Code:

$where_str .= " GROUP BY p.products_id, tr.tax_priority";

with

Code:

$where_str .= " GROUP BY " . $select_new_str . ", p.products_id, tr.tax_priority";

returns the correct results.
I have not tested it to see what else i tmay have broken

v139h What version of Zen (from last 5 years) has the most plugins and most current users?

Feznizzle — Thu, 21 May 2026 22:07:18 GMT

Hi,

I'm looking to update a huge website with 20k+ products.

The main goal is just to (1) install responsive template and (2) be able to feed products to Google Merchant. But the existing site uses tons of plugins (Ceon URI and EPpop4 being the most important) so I will need some options if those tools must be replaced.

I don't care about being on the cutting edge (ZC 2.2.2), I just want reliability, options (lots of plugins/templates), and support (active users I can consult with on this forum).

Can somebody tell me which ZC version fits that bill?

Thanks!

v139h Are there mobile templates for a VERY old ZC v1.3.9h?

Feznizzle — Thu, 21 May 2026 21:43:43 GMT

Hello!

The site I'd like to update was one I built more than a decade ago and then sold to a friend. It has more than 20k products and has been chugging along just fine, but it is very much in need of a face lift.

My initial thought was to bump it up to ZC 2.2.2 and slap a modern template on there. However, the original version has tons of plugins and gobs of custom php. When I did an Advanced Search for 2.2.2 plugins, the list was CRAZY thin!

I don't even remember what plugins the site uses. Can someone remind me how to generate a list? The main one I was hoping to see was EZ Populate4 (or newer).

Anyway, given the lack of plugin, I thought just skinning it would be enough to achieve the main goal:
Removing the SEO penalty for not being mobile friendly.

Any thoughts? Are modern-ish templates (CSS, mobile) available for sites that old?

Before anybody lectures me, yes I am aware of security risks of running outdated php. The site has been doing fine so far, and today I took some measures to boost that, best I could. :)

HS Code Mod?

gsh68 — Thu, 21 May 2026 16:12:40 GMT

Currently running 1.5.7.c but will be upgrading soon.

Is there a mod to add HS codes to zen cart products?
New rules for selling into EU come into effect on July 1st and in order to continue to use ZC for EU customers I need to be able to add duty to orders based on the product HS code.
I am planning to start shipping DDP into EU to simplify matters as the new rules complicate the current system with collecting VAT on orders below 150euros. It will be much easier to collect VAT on all consumer orders regardless of value and collect the duties applicable at the same time.

I was hoping there might be an all encompassing mod that would handle this, what with the recent issues with US removing the deminimus threshold and adding new tariffs etc, but after a search it seems the only one suggested tends to be CEON Advanced Shipper, which doesn't have great support.

International commerce seems to be getting more complex - I think this is an area that should definitely be on the devs radar.

TIA

v210 POSM - How to set product for POSM tracking

Dave224 — Wed, 20 May 2026 18:35:22 GMT

I've added a product with attributes to a catalog and want POSM to track the product variants. When I go to admin/Catalog/Manage Options' Stock and select the category and click Go, only one product with attributes in that category is displayed and I don't want that product tracked. None of the other products with attributes are shown in the dropdown, including others tracked by POSM and the one I just entered and set attributes in the attributes controller. What am I doing wrong?

Thank you!

Dave

v201 Sort Order on Brand Page

nicksab — Wed, 20 May 2026 01:46:10 GMT

Is it possible to have the Sort Order Filter to display product in dated added order (new to old) on Brand Page only?

I see in admin you can specify for all product, new product....by specifying it in Configuration - > Product Listing -> Sort order Default

None of these applies top Brand Page only and the Sort Order Default Product Listing changes it for all pages.

Thank you in advance for the assist

I enabled MFA for a client using ZC 2.1. Several users now get a too many redirects error when logging in. In troubleshooting, it only happens with users who are not SuperUsers. I don't see this mentioned as a fix in 2.2. Is this an unknow bug?
