I have all my posts in separate categories. The “Read More” link is white the same as the page color. When i change the link color under topography it never changes. The same thing happens with the Post Comment link. Any help would be nice.

I don’t see any issue with link and button on your website. Could you please show me some screenshot how website appears to you because it works perfectly fine for me.
