Photos in center of frame

Hi,

That's because of the CSS of your template.
It forces the display of the images to be "block" instead of "inline" and thus the "text-align: center" on the area is not taken into account.
Add that CSS code on your website to counter the CSS of the template and the category images will be centered:

.hikashop_product_listing_image {
    display: inline !important;
}

Hi,

The with of the frame depends on the number of columns you configured in your menu item settings.
The height of the frame depends on the height of the content inside.
If you wish to increase the height of the frame you can use CSS.
For example:

.hikashop_container {
    min-height: 380px;
}

.hikashop_product_quantity_main table {
 display: inline !important;
}

Hi,

That's because on one page you have a listing with 4 columns and on the other a listing with 3 columns.
Since there is more width available on the listing with 3 columns, each frame is wider.
To avoid that, you need to edit the corresponding menu item in the Joomla menu manager and set the number of columns to 4.

The "Quantity input method" setting in the HikaShop configuration allows you to change the layout of the quantity input area. The current layout you have for that area is an old one.

Hi,

I'm not sure what you mean. What is "a fail on Google index" ?
Lately, someone reported that issue: www.hikashop.com/forum/product-category-...thout-canonical.html
But I'm not sure it's related or not as I don't understand what is the problem you have. Because, the fact that the contact pages are not indexed is normal as you don't want them to be indexed by search engines.

Hi,

I'm not sure.
Could you provide some screenshots of the information you get about the contact pages in the search console ?

Hi,

I don't see any errors there.
It's just a list of the noindex URLs. And that's normal you see the contact form pages there as you don't want them to be indexed for each product.
So there's nothing to worry.
