Can’t edit page

I’m having trouble getting edits to a page on my website to update and then show on my website – I can update other pages, but not this one.

The edits appear in the Dashboard editor as having been applied (as in, I update and exit, then go back in and the edits are there), but they refuse to show on the website.

I am trying to do three things:
1. Update an image that should then scroll between it and another image. It now only shows as the unchanged image as a single static image.
2. Trying to add text to the page (but it isn’t showing).
3. In the second set of scrolling images one of the images is showing blank thanks to a broken link. I have updated the link but the image is still showing blank.

I’d appreciate any advice on how to get my edits to work! Thank you =)
