Hi There
I’m afraid I was like you, I tried everything I could think of, and in the dashboard my front page seemed the same as always and when I tried to change it nothing happened.
I had to end up asking someone else to fix it, as I got no replies from the forum. I still don’t know how he fixed it as I haven’t seen him since and he didn’t have time to explain it that day.
I usually Just update wordpress, rather than the updating the actual theme, and I had updated the theme by accident that day. He advised me to do a child theme for the whole of my website in case it happens again, but I haven’t read up on that yet.
I’m sorry I’m not much help.
