Guys before five days ago I add https:// to my website which is old more than three months. After adding that to my website, all static was changed in my webmaster tool, and now nothing is showing an index page. As well as when I added https:// into Yoast SEO plugin then Yoast site map also went down. I reinstalled it, but still, no luck and sitemap is not working. So guys pls guide me to fix this two matter.
