Hi, I’m investigating the issue yet. There is something that catches my attention, the preview does not work, for example I add a cover page or text, the automatic save fucniona correctly, but when you click on preview the changes simply do not show them. Only when updating generates the changes. I am working with wordpress 5.0.3, GP Pemium, GeneratePress Child and localhost mode. This is normal ?.
Thank you for the attention.
