Title in post is showing up in the background and having trouble formatting

Okay I am currently using the Highend Theme on wordpress. I have two problems, one being, the titles in my individual posts (the page with the actual content) show up in the background, meaning you can’t see it but if you highlight it you can, basically white font on a white background. How do I fix that?

Two, I want the titles for my posts on the main page to be on TOP of the featured image. Right now the titles are displayed underneath the featured image.

Thanks for your help
