Sometimes, when you try to add a product to your cart, it redirects you back to a Cookies Page, which is annoying.
So, here are two ways to fix this :

1. 1) Increase Cookie Lifetime

– Go to System –> Configuration –> General –> Web –> Session Cookie Management –> Cookie Lifetime = 5400
– By default, Cookie Lifetime = 3600. You can make it more than 5400 and try if it works.

2) Disable redirect to enable-cookies CMS page

– Go to System –> Configuration –> General –> Web –> Browser Capabilities Detection –> Redirect to CMS-page if cookies are disabled = No
