So, today after installing wordpress to my website (www.harshreviews.pro) everything was fine, i started editing the site etc etc, and after a while when i try to enter the site there is this error “Conection is not private”, Someone here told me to go to my administrator setting page and change from the “https://harshreviewspro.000webhostapp.com” to "http://www.harshreviews.pro"
And that helped so much that now not even the administrator page i can’t enter, when i go to “harshreviewspro.000webhostapp.com/wp-admin/” there is the same error with “conection is not private” 
And now my website looks awfull, and i don’t know why
