Blank page when viewing feed

Hi…

Sorry if this is covered somewhere on the help support.
My feed works on the Woocommerce Product Feed for Google Merchant 0.35 page as it shows the last 3 products, but when you click the feed link it just redirects back to a blank page.
I have tried changing the permalinks but it doesn’t make any difference.
I am using permalinks on Common Settings post name and Product permalink base shop base with category.
I am using the enfold theme.

Seems like a fantastic plugin.
