I downloaded Paper Plane - Minimalist WordPress Blog Theme
This theme has several serious problems
1- “Coming soon” page will not be displayed properly
2- The AMP system does not work
3-How can I change the position of the share buttons in a post?
4-how can I activate the advertising system (similar to the banner ads in the demo) Is Changing Your URL Structure a Bad Idea? - Paper Plane
Of course, these problems have been reported to the author both by email and in the comments section of this product in the Forrest theme
please consider it.
