Hi,
We have a French support section if you want.
www.hikashop.com/forum/5-support-en-fran...french-support-.html
1 - This problem is coming from your template which does not handle the bootstrap popup.
Please change the popup mode to "mootools" in your HikaShop configuration.
2 - It is a minor CSS problem.
You can override the HikaShop CSS in order to change this rule:
.hikashop_product_quantity_field {
width: 25px;
}
And give more width to the quantity field.
3 - I do not have access to this page in your website so it will be more difficult for me to give you a precise answer.
What exactly is not working ?
Regards,
