Hello,
I have been through some issues when I want to change my page attributes and when I want to select layouts to the specific WooCommerce (such as the store menu page) from Default to Full-Width (no sidebar) option.
This issue is happening with an incompatibility with only the WooCommerce Theme.
I have talked with a person from WordPress and he recommended me to post it this issue in this forum.
Could you help, if you will?
