WP Shopify backend pages are all blank

Hey there,

I recently downloaded and set up WP Shopify for my store https://www.yochi.com.au

I am trying to configure it however the connect, settings, tool, license and help tabs in the back-end are all completely blank. The products and collections tabs have the Almost Ready sign with a link however that link just goes to the settings tab which is blank. I am running PHP v.7.0.33 if that helps
