I'm in need to create a custom hook in a specific cms page in order to show various instances of the same module (sliders of products). I tried following this guide here http://nemops.com/how-to-hooks-prestashop-cms/#.VtbJR8Q0mdU but when I go to the backend the hook I named "Vert" doesn't show.
I'm using the latest version of prestashop, with cache disabled and I forced the recompilation of the tpl everytime a page is loaded.
