Hello,

You may add this code in Custom css:

    text-align: center;
}

Hello,

Please check now.

Please check now.
If problem persists, please describe it with more detail.

You’re welcome!
Because you created Size and Color attributes manually, these are no default elements.

Sorry, but we do not have a ready solution now.

Check the destination folder of FTP. At present, we can see only empty folder http://prntscr.com/gk7hax
We need access to your WP root directory.

Hello,

Install and activate default WC theme Storefront and check if this issue appears with our theme only or with default theme too. We’ll be able to help you only in case problem appears with our theme and everything works fine with the default theme.

Regards

We do not have such option in our theme. It’s possible to implement only by additional customization. If you need help with this you may contact WPKraken team because theme support does not include additional development service, unfortunately.

Hello,

What plugin do you use to translate theme?
Go to Settings > Permalinks > try to re-save permalinks, check if this helps. If not – provide me temporary admin panel access.
