Since WooCommerce released 2.3.x there is a huge conflict with the Blanco theme (all products and product categories disappear), so I had to revert to WooCommerce 2.2.11. I have manually reverted twice via FTP to replace the plugins/woocommerce folder. However, I discover that WooCommerce has mysteriously upgraded itself to 2.3.x without anyone choosing to upgrade the plugin. I have not been able to find any setting in WooCommerce (or WooDojo) that would disable the auto upgrade.
Any suggestions?
