I tried to change the button image to a custom one (https://www.twosevenths.com/wp-content/uploads/2020/11/118119834_609191269792923_1014522750142962911_o.jpg)
However, the image is not shown. Neither did normal nor hover works.

Sorry for the late reply. I checked out your demo page but it seems to be down.
Do you have an updated demo page so I can check it out again?
