Product details asks for authentication

-- url of the page with the problem -- : lojadocaopreto.com/index.php/verificacao...961-almeida-mario-de
-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.4
-- PHP version -- : 5.4.42
-- Browser(s) name and version -- : Chrome
-- Error-message(debug-mod must be tuned on) -- : Asks for authentication

I upgraded from Joomla 3.4.8 to 3.6.4 . No change in hikashop version, 2.6.4

After I upgraded I started to hava a problem with only one category,

When I try to access product details from that category, it appears a form asking for authentication.

I can't figure out what happened.

For instance, if I access to lojadocaopreto.com/index.php/novidades and choose any product, i'm forced to authenticate to see the details of the product

But if I access to lojadocaopreto.com/index.php/antiguidades2 and choose any product , I don't have to authenticate

Both menu are public

Thanks

Hi,

From what I can see, the issue is that you have invalid canonical URLs in your products and you've activated the "force canonical URLs on listings" setting of the Hikashop configuration.
Turn off that option or empty the canonical URL of these products and it should work.

Thanks

You were right.

I had "use canonical URL and generate it if missing" option activated.

I cleaned the field and everything stated working.
