Keyword density check comes back with Javascript?

Every keyword density checker i put my webpages through come back with the same results as below



My website is nothing to do with javascript by the way..how do i sort this so the keyword density can actually read the text on my WordPress site?

any ideas anyone? Ive also noticed when i post an answer on Quora with a link to the same website, the link doesnt scrape any of the content form my website just says the following..

"this page requires javascript to work properly. please enable javascript in your browser or use a browser with javascript"
