All Links to Single Post Are Semi-Broken

My links are not working properly at my two newest sites. When you hover over the post title, the hover effect does not show up; however, if you click on the link, the hover effect then shows up. Clicking the post title does not open the single post, which is the desired effect.

Perhaps the strangest part of my problem is that this problem is also occurring within the admin panel – not just in the front-end view.

First is: Estes Park Horseback Riding

and second at: https://michaelecharles.com/category/all/

Any help is grealy appreciated.
