The issue persists for me with Storefront (no child theme) 🙁
The 2.0.1 version also renders my site unavailable (code 500). I can only fix by FTP uploading Storefront 1.6.1. I have the latest WP & WooCommerce. My only plugins are Google Analytics, Revolution Slider and Ninja Forms. I have attempted reloading Storefront several times with the same result.
I had a similar experience upgrading to 2.0.0 today, and just joined here to see if others had similar issues. In my case, I immediately got a “500 Error – Website Not Available” message. All my other WP sites (non Storefront) on the same server worked fine.
Since I could no longer access the admin portion of my site, and had to FTP upload Storefront 1.6.1 to resolve the issue. Once that was uploaded, my site was working fine again. I may try again, or wait until 2.0.1 or something similar. My site is pretty bare bones, and only uses Woocommerce, Storefront and a few simple plugins.
