I have been altering the phone version of my site and my breakpoints responsive widths seem to be working without a hitch, butttt..... at some responsive widths a large white space that the bottom of the page is created and I can't get it to go away. I can't get the page height to match up with the content height on some widths. There doesn't seem to be any extra text outside the widths. Unsure how to adjust anything else. I turned off sticky footer. double checked content to be inside the breakpoints.
Depending on how you set it all up, change the height of your document in the breakpoint where you have issues to, let´s say 500 or less, if your design (footer-header-content) allows so. To do this go to page properties in that breakpoint and you should be pretty much done.
Delete all unrelated pages and elements from your site, save it under a new name, upload this small(!!) .muse file to Dropbox, CC Files or a similar file sharing service, and post the link here. Then we can have a look. You may follow these instructions: https://forums.adobe.com/docs/DOC-8652
