On product page - "Add to Cart" button disappears after manually entering quantity

[nth-solutions]

On the product page, there should be two options to change the quantity:

1. press the + and - buttons next to the quantity box
2. manually type in the quantity you want

The first option works fine. When I try to do the second option, however, it doesn't work. When I type in a number and click elsewhere on the page, it updates the price but the "add to cart" button disappears. There are no combinations or customization options for this product - it only comes as is. 

 

What can I do so that when I manually enter the quantity I want, the "add to cart" button doesn't disappear?

Sounds like a javascript error. And it is likely specific for your theme.

 

So you could ask the provider of your theme.

 

If you want help here it would help if you provide a link to your shop and tell us which version of Prestashop you are using.

I am using the default theme in version 1.6.9

 

Here is a product page from my store

I don't see any problem with figures. The only problem is that when I type "7" I see a long row of zeroes behind the price. 

 

So I assume that either your problem is browser specific or that it is specific for your computer/browser combination. In the latter case cleaning the cache of the browser should help.

I have same results as music master.  On occasion as we develop a shop the 'browser cache and/or cookies' need to be cleared from the browser we are working with.  If you have not cleared browser cookies/cache please do so and repeat your test.  (my test was using chrome browser)
