OpenCart Community

Hi

I have researched modules and extensions for Opencart but can't seem to find a solution to this.
I wish to have the website load as normal, I can browse information pages, but when I click on any category or product I am brought to the create account screen and must register to go any further.

How can I add the login code to every category and product page to ensure only verified, logged in customers can get access.

thanks
FG

Maybe that searching on restricted categories might help
