Can you provide more detail on what’s going on?
We’re here to help, just need more info like a reference screenshot of the error.
Like Ankush said, please provide us with details of any error messages that you get when you publish your sites using Muse. Also, can you try exporting your files as HTML and uploading them using Filezilla? https://filezilla-project.org/
