Can not Insert site

[An Ho]

Please help, I do love yours extention, its live saver for me. 

But recently, I cant not insert site to work, after i click on "Insert site", browser redirect to "https://stable.edfiller.in/", not to the former site like before. I've tried many brower (chorme, firefox). My computer run on Window 10. Do I have to do anything else?
