All product details disappear

I had high hopes of being able to customize my WooCommerce shop with this plugin. Was a little disappointed to see that most of the customizing is only available in the $19 Pro version, but was going to buy until I noticed that all the prices disappeared along with the product details.

Might be a fix for this, but I hesitate to use a plugin which is buggy.
Maybe I will try again some time in the future, but not today.
