I have a problem with my categories somehow all the categories besides English are no displaying correct in the URl and we are having a 404 error can you help?
In your staging site, I deactivated all non WPML plugins and now everything seems to be working as expected when clicking on product categories. Please confirm, and then to find the conflict, activate the other plugins one at a time or just a few a time to see when the issue returns. Let me know if the issue does return which plugin you found to be the conflict.
