1. Webmastertools Structured Data Conflict

If the Rich Snippet Testing Tool shows conflicts, please try the following things:

- Disable the extension, flush the cache and try the URL again in the Google Rich Snippets Testing Tool

- Make sure there isn't already markup data available on your store. If so, you have to first remove this markup data as it conflicts with the schema.org snippets data

- Make sure you don't activate the Rich Snippets in the Add-this extension

- Make sure you are using https and http in the right way in the Webmaster Tools
