The same situation on my site could you please analysis of mine. even though I have numerous links both internally & externally! [SPAM LINK REMOVED BY MODERATOR.]
You must know, that this thread is from 2017. Since then Muse is under EOL - noone from Muse will have a look. Google changed. Muse is, at least, outdated with its code which may lead to your result. You should either watch out at google helping sites on what to do or talk to your hosting - these companies can help, too or hire an SEO expert with your issue.
Also I recommend to open a new thread so the chance might get better to have a forum member to watch for your issue.
actually not even a Muse made site mate
This is very suspicious given that your site isn't even made with Muse. It's built with WordPress which is totally different.
