i have problem, when i change the declination on my product page on prestashop 18.104.22.168
when i looked for the error it look this error image
any one can help me please, im using prestashop 22.214.171.124
I had the same error: "Cannot use object of type Product as array".
In Prestashop 1.7: "Objects are no longer passed to Smarty. We only use arrays now." (http://build.prestashop.com/news/module-development-changes-in-17/#general-information)
In my case, it was a module 'productcomments'. He overwrites the "product" index and changes "array" to "object".
