error not indexable because of canonical?

I tried using a firefox add-on that checks my SEO, it dectects that my website’s post is not indexable because of error this pag has canonical URL. I noticed that when I click a blog post from my homepage’s feature posts the URL becomes https://www.mysite.com/mypost#more=124 it adds a “#more” at the end I cant figure out how to remove it. Even if I delete #more and refresh the page my post loads fine. What I can not understand is what’s causing to add a “#more” on my url if you click the post from the homepage. My website is https://www.igeeked.com please help thanks!
