Advice please! 'Published' page updates but they aren't showing up?

Newby here, I haven't used website creation tools or editors in 10 years, and I have found myself in a pickle. I'm trying to add content to a page on my website, but after i press "publish" with it set for "now" it doesn't show up on the actual page.

I even checked a few hours later, just in case, and it still wasn't there. has anyone else had this issue? or does anyone know how i might be able to fix it?

Thanks
