Hi,
WCFM dashboard display changed a lot in recent time.
Now default save button are visible in floating mode.
Please go through this once – https://wclovers.com/blog/wcfm-dashboard-as-site-template/
You may also check any of our demos once to know the changes – http://wcmp.wcfmdemos.com/my-account
I think there hs some simple CSS issue in your site, possible site footer z-index too high and it overlaps WCFM Button Bar.
You may also disable this float button and may keep old look, kindly look into WCFM admin Setting.
Please know me if I can help you in some other way.
Thank You
