I made my home page in muse because I'm not that good at css, but because muse is very limited I added some custom php files afterwards but when I upload the export to my host + the custom made files I can't acces them.
Imgur: The most awesome images on the Internet
update: it only doesn't work if it's in the same folder it will work if you're in a child folder
Please check this thread - Including .php file in Muse bit old but might help to resolve your query.
