My Add to Cart Button in Product Info Does Not Work in Chrome & Firefox

Hi there,

my website is:
http://multikopterdukkani.com/store/

zencart ver: 1.5.0

I have a problem.
When I use Google Chrome & Firefox, "add to cart button" in product info does not work. Also in shopping cart I can not edit quantities. For example if there are 2 pcs of the same item and I try to update it to 1 it goes back to 2 pcs again.

Everything works fine with IE 9.
Because of that I lost a customer today :(

What could be the problem?

Thanks in advance
Cenk

You can try switching to the classic template and see if this is the same

If not, when you reply - scroll up and read - then supply the additional information that will assist us in troubleshooting this

Thank you for your reply.

When I switch to classic template everything seems OK. So this is a template problem.
How do we fix it?

Cheers
Cenk

One would have to look at the files contained in the template folders
Rename them one at a time to xxxxxxx.off then check to see if it still broke
Rename back to xxxxxx.php and move on to the next one
Hopefully, you will locate the offending file in this way and can then post back with what you have found

You might also contact the people who designed your template, if they offer support. This may be a known bug.

I just tried in FF on this page http://multikopterdukkani.com/store/index.php?main_page=product_info&cPath=17&products_id=167
and it worked fine.

Also tested in Chrome - works for me.

I did as you suggested for every php file that I could find in all of the folders one at a time but with no luck. Nothing has affected the problem...
What confuses me that it works fine with IE9. Also why add to cart button in some of the products works and some do not?

Like this:
http://multikopterdukkani.com/store/index.php?main_page=product_info&cPath=17&products_id=207

"Products Quantity Box Shows:" set to: "Yes, Show Quantity Box"
"Product Qty Maximum:" set to "0" for unlimited.

I got a reply from the designers:

"It is the same template files used for some time and I have checked without issue. Also, I have never received any feedback from any user regarding this.

I have a feeling this is not related to our template, because our template does not have any file related to shopping cart. All files related to cart are from the DEFAULT TEMPLATE. Our template have only a few files related to header and footer. You can browse our template folder and compare to the default template folder.... you can see we have only a few template files.
(Zen Cart automatically use files from the default template when a custom template does not have the files).

Please check what 3rd party ADD-ON you have installed that is related to cart or checkout."

Thanks

Yup. That product works.
But try to add this when you have an item in your shopping cart:
http://multikopterdukkani.com/store/index.php?main_page=product_info&cPath=17&products_id=207

And please try to update products in your shopping cart using Chrome of Firefox

If you open up web console in Firefox under Tools you'll see you have a lot of errors loading your product info page. I would start by fixing those.

NEVER a good way to upgrade especially with 3rd party addons
You might check them for any updates from 1.3.9 to 1.5.x

I fixed 2 of them but other two still remains...

Error in parsing value for 'background'. Declaration dropped. @

I don't know how to fix them :(

I checked it but v1.5.0 is still the only available version in Fantastico deluxe on my hosting company (which is total choice hosting)

What I am saying is that these "one click" upgrades are not the recommended method for upgrading and are fully unreliable

Oh. Sorry. Misunderstood.
But on the other hand everything works fine with Classic template....

That would be due to it using default coded files

You will need to determine what template override files need to be updated as the "one click" upgrade does not upgrade these custom files

Thanks Kobra. It looks like this will be waaay over my head. So I started a fresh custom template and see what happens....

Finally I found the problem.

I installed "Shipping Estimator sidebox" a while ago.
Today I turned off all sideboxes one by one to see if there is a conflict. And vola Shipping Estimator off, problem gone. Everything seems to work fine right now.

So "Shipping Estimator sidebox" and my template Premium 6b from zenflavor don't like each other...

Cheers

Glad you have this sorted

So to summarize, for future searchers who might read this: if an action such as "Add to Cart" doesn't work, try the default template. If it works there, figure out what's broken in your template by disabling specific things in your template such as sideboxes until it does work.

Glad you're all set, @yellowaircraft.

Exactly.

I have searched several threads and spent hours looking for any help. My problem is that Zen Cart is allowing customers to place more of an item in their cart than is in stock. It is also allowing them to checkout. I have Admin>Configuration>Stock - Allow Checkout set to false, but to no avail. I recently upgraded to v1.51 from v1.39h and din to have this problem before.
If a customer placed more if an item in their cart than there was stock for, the received an error message and had to change the quantity before checkout. The new version does not prevent this, or I have something set wrong. Could someone please point me in the right direction? :blink:
