Cant get rid of loading icon on home page

Hi Guys,
Im getting a loading icon on the home page anytime I open my website. Any ideas how i get rid of this? The site is set up in a sub domain folder so that mite have something to do with it but i have two separate installs of wordpress. I have tried the url in an old browser and there is no error. But in newer versions (safari and chrome) it doesn’t work.

The site is https://www.lacavewinebar.com/wineschool

Thanks again
