If you did change anything in your html with anything else than muse, then muse always still uses the fonts you once used with muse. So it makes absolutely no sense to make any changes different from within muse - as long as you want to publish via muses "publish to ftp".
If you want to do so, then you must find all fonts, which are now kind of pink backgrounded, once this made visible wether there's a webfont or not, you must then replace these fonts with a webfont - a self hosted webfont, I recommend.
If you were lucky enough at the time you created the website and knew how to deal with paragraph styles, then it may need less time to make those changes, because the paragraph style only must be changed once for all pages.
By reopening all pages after paragraph-style-change, all fonts should be at its place.
If you didn't do so, well, …
Although Nancy is very keen in using html and is obviously quite good in coding, she has still no clue how muse works. So to tell users to do any changes with any code editor in a muse-file (it's just html code, created by muse), may be professional, it does not help here.
I hope that helps …
