[נפתר] Incorrect category links

Hi,

Please connect this thread to a human.

All the links in the menu were working fine, client was adding new products today and all the links in the product categories suddenly lead to pages with an "error page" in the Polish version. What's going on? I'm attaching a screenshot. In the English version of the site, links to categories work fine, but when you are in a given product category and switch to the Polish version, an error page also appears.

Best regards,
Tom
