Yes! I managed to resolve the issue yesterday night: seems that your plugin was in conflict with another, named:
“eCommerce Product Catalog for WordPress”
Yet I don’t understand how this might happen all of the sudden, since all our staff swears that didn’t do any update on either of these, or WooCommerce, or WordPress :/
Do you have any hint about this, or how I can make those plugins live happily together?
If not, we can consider this topic closed, thanks ??
