6 demo BO, on the other hand I couldn't scroll right down to base of the side menu to accessibility the module. This is because by default the menu won't scroll, so you're able to't look at the back links in direction of the bottom. There's a free module available to https://www.presta-addons-modules.com/en/opencart-seo-automatic-google-rich-snippets-json-ld-integration-opengraph-twitter-tags-schemaorg.html
