Customer Unable to "Buy Now" via Manufacturer List

**PanZC2020** · 14 Jun 2018, 03:55 PM

Site: https://homepromedical.com

ZC Version 1.5.1 (but the database version it stated Version 1.5.4)
PHP Version 5.6.36

Suspect plugin related to this problem: Ultimate SEO (?)

---

The website can buy products when customer browse normally.
The buy now button has this link, which is working.

Code:

https://homepromedical.com/cart/aids-for-daily-living-c-135/?action=buy_now&products_id=674&sort=20a

When customer browse products via Manufacturer menu (on left side, scrolled down, below "New Product" box), they can browse products.
However, customer is unable to purchase products in this method as "Buy Now" button lead to 404 error...

Code:

Not Found
The requested URL /cart/index.html was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

So the link on "Buy Now" button is this...

Code:

https://homepromedical.com/cart/index.html?action=buy_now&manufacturers_id=4&page=1&products_id=674&sort=20a

If compared together...

Code:

https://homepromedical.com/cart/aids-for-daily-living-c-135/?action=buy_now&products_id=674&sort=20a
https://homepromedical.com/cart/index.html?action=buy_now&manufacturers_id=4&page=1&products_id=674&sort=20a

Seem the additional of "index.html" lead to 404 error.

This surely happen every minute as the 404 error stats shown...

Code:

/cart/index.html -14,949

Which is really a lot of hits & misses.
Surely, lose couple sales right there due to this 404 error.

Would need to dig deeper on whether sales were even a goal of the visitor as could be a bunch of bots just testing the water. At any rate, yes the URI Rewriter and its setup are having an effect on this if not also the way the link is generated at that page. I'm not highly familiar with the configuration of it; however, there should be a way to either disable the uri rewriter for manufacturers or possibly by meeting some other criteria. Considering that using ZC 1.5.1 with what appears to be a database of 1.5.4, presumably whatever issue is causing this has either been discussed or addressed in the forum for Ultimate SEO URIs. Would suggest perusing that thread.

I decided to continue on this in Ultimate SEO topic...

However, I am not 100% sure if it is truly case by plugin or mixed of Zen Cart and plugin configurations...

I don't see how it can interfere "Buy Now" button.
So I wonder how "Buy Now" button generated... why it generated 2 different ways from regular product listing vs manufacturer's product listing?!

No override were used for these files in "my template" folder.
