I created a page for a post and another for a blog using the latest Version of Nicepage on the Desktop.
The Blog page has a Blog Block which is created by importing the Nicepage Blog template.
The Post page is created in a corresponding fashion.
I exported the Theme for JOOMLA 3.9.17. Unfortunately, the Blog and Post Blocks disappear from the project when I want to call then up for modification.
What am I doing wrong?
