WP Catalogue – product image border on hover

This is correct:

.wpc-img:hover {
border: none !important;
}

It might be struggling because it’s in a child theme… Try putting it in the parent theme temporarily or hardcoding in the plugin stylesheet just temporarily to confirm if this is the reason it’s not taking affect… let me know

I changed it directly in the catalogue-styles.css file and still no luck. Could it be found in another file?

If I select “Clear” under Theme Color in Settings it reverts back to black. Is the border being set by this file?

No so the problem is that something is overriding those styles from both your own theme css and the plugin css. It could be another plugin, so try deactivating everything else and see if that solves the issue. Sorry there’s not much more help I can provide on this one – you just need to work through the site logically and find out where the rogue css is coming from

If you run any caching plugins or via .htaccess, try disabling caching and delete your browser cache then make changes to CSS. Might be the problem…

There’s some css at the bottom of index.php file (plugin catalog) that define img border behave on hover.
