masterstudy theme is not showing preview

helo, i have successfully installed and activated masterstudy theme. but its not showing preview. it took more thn 30min and still loading.


For any technical query about theme functionality the best choice will be contact theme Author and let them know How to Contact your purchased theme Author, theme author will be happy to answer your query.


In my case it is the non-certification of SSL on the pages of my website with the theme MasterStudy.
