Tag Catalog not working

Hi, my Tag and Catalog is not working properly, please take a look at this site

https://thisisethan.com/blog

if you click on any Tag or choose anyone from Catalog on the right hand side bar, it will direct you to the blog main page, but not the Tag or catalog that you chose, the URL seems working fine with /blog/TagName or blog/CatalogName, but the page remains at the main front blog page….

I’ve been look up forums and help pages, but it seem hasn’t resolved yet, please help anyone please! thank you for your time and help. cheers
