Hello, I'm new to prestashop but I already developped web site.
I want to show The Hookleft in product page. But i can't.
I tried to manually call the hook in product.tpl but it does not work.
I also tried to manually change the value of $ left_column_size in header.tpl but it had the effect of only display the <div> with this one with nothing in it.
I have not found in the back office either
Thank you in advance for those who are looking at the issue
