Updating Jetpack from v3.0.2 to v3.1.1 broke Woocommerce's base shop page on my test site. Woocommerce was unable to initialize on the page, and all that appeared was the header and footer, with no content (not even empty space) between them. It initializes correctly for category pages and product pages, only the base page fails.
After exhausting all other options I knew to exhaust (clearing out custom css & disabling each Jetpack module, disabling other plugins, etc), I reverted back to Jetpack 3.0.2 which resolved the issue. This is only a temporary solution though.
I love using Jetpack and I'd like to continue using it throughout future updates, but without knowing what exactly was causing the problem, I don't know how I'll resolve it if it persists through future updates.
Here's my currently active plugins. All are up-to-date except Jetpack:
Custom Sidebars, Jetpack (3.0.2), UpdraftPlus, Woocommerce, WordFence
Here is the URL to the test page where the issue occurred:
If anyone knows how to help, it would be much appreciated. I'll do whatever I can on my end to help get to the bottom of this. Thanks.
