hi,
I installed falang to translate the content of hikashop (products and categories). I translated some products, and they are well displayed in english and arabic but if I click on arabic product it send me to the product in english.
I attached you a pic, as you can see the link displayed on the bottom when I scroll the mouse over arabic product is in english. how can I fix this problem.
thank you

Hi,

This means that you have entered the English URL in the "canonical URL" field of your product and that you have the "force canonical URLs on listings" option turned on.
Change either and it will work.
