I tried to create a new blog page and assign the Masonry Blog template, but the list of templates in the Edit Page section only shows me a list of Home templates under full templates. Sections and columns is also empty.
Not sure whether I missed something during installation or if someone happened to delete those templates.
Is there a way to import/restore the complete list?
I hope you are well today and thank you for your question.
Masonry Blog is not a template but blog style which you can choose from page blog settings in the page where you have set page Template to Blog as shown in the attached screenshots.
