Thanks in advance")* Hi, If you see SEF URLs on the listings while you have the SEF system deactivated, then it means that there is a caching issue. Please turn off all the caching on your website. Also, do you use a SEF extension like sh404SEF ? Such extension can have a cache of the URLs and it can happen that the cache is not up to date and it then create such 404 errors. Clearing the cache of the SEF extension can help in that case. And yes, having canonical URLs forced on listings can also cause such issue but you say it's deactivated so it's not coming from that. Finally, deactivating the "remove category and product ids" setting of the HikaShop configuration can also help when the issue comes from the alias in the URL being invalid. So try that.

Thanks in advance")* Hi, only a part of the problem was solved: by deactivating the "remove category and product ids", I had all the products URLs in listings correctly working. But the issue in the products displayed via the content tag insertion plugin remains: in SEF mode, the URLs simply do not work (and have a quite different structure from the same product as displayed in regular listing, as I wrote before: [domain]/it/component/hikashop/prodotto/[product_name] instead of [domain]/it/prodotti/specialita-farmaceutiche/[id]-[product_name] in non-SEF mode, they still have SEF URLs. About your suggestions: > If you see SEF URLs on the listings while you have the SEF system deactivated, then it means that there is a caching issue. > Please turn off all the caching on your website. Joomla cache was already disabled. > Also, do you use a SEF extension like sh404SEF ?

Please note, though, that I skipped disabling joomla native components (I did it only on external components). Should be worth trying to disable also these ones? Could be of any help finding the source of the issue remarking that also in SEF mode these URLs are not working (they are different from the ones in the regular product listing)?
