The plugin “WooCommerce Customer/Order CSV Export” from WooThemes works with the theme Twenty Thirteen. It also works with the theme Neigborhood. This is not the issue.
The problem is, that for some reason WooCommerce Customer Export plugin disables the functionality of the Swift Page Builder. Now, when I enable the plugin WooCommerce Customer/Order Export, the editor hides the Swift Page builder. Now, I have already got in touch with WooThemes about this issue => They referred me back to you. Also, they suggested that you can get in touch with them about the issue.
Can you reproduce the problem? Do you need a login for my staging environment?
Thank you, I hope we can fix this soon.
Best, Robin
