Fatal error:

Hi there, the plugin should work for any site – it sounds like you need to increase the PHP memory limit as described here: https://docs.woothemes.com/document/increasing-the-wordpress-memory-limit/

Also, out of curiosity, does the site in question have a lot of existing orders?

HI stesod,

We released an update a few days ago that will avoid these errors for most large stores. If you have a chance, we’d love for you to give it another try and let us how how it works for you ??

Thanks!
