OK I’ve done several tests. When I use woodmart’s swatches feature instead of Getwooplugins one the problem disappears. But when I use Getwooplugins and another theme than Woodmart it works also. So the issue comes from an incompatibility between woodmart and Getwooplugins. The problem is that I prefer their plugin than woodmart’s built-in function (Swatch image is immediately displayed in the main image area when I click on the icon instead of waiting to select both variations, the length variation button is nicer etc…). So I’ll try to see if they could correct the issue.

If it’s not possible could you give me the CSS to mahe the swatches bigger (they are really small) and in a square with rounded corners instead than a circle ?

Thank you.
