Product Description Editing Box Is Not Showing In My Prestashop Backend

[Ray]

Hello, product description information box is not showing in my backend. Please how can i solve this?

Secondly, how can i see where the prestashop codes are so i can insert a desired payment gateway?

How can i also add bank transfer details to my shopping cart page?

Finally, how can i add a form page to my prestashop or a customized registration page or add some more questions to the default registration page by prestashop?

Please help. Thanks

There is probably some js conflict. You have to check your chrome console.
