Entire site Links not working

I think my entire site it screwed up!

I can’t click anything (nav. menu, sidebar, hyperlinks, etc.) without being redirected back to my sites main URL (https://MeaganVisser.com)). My settings are set so that the front page shows my latest posts which is what I want. Eventually I want the main URL to have an image on it, but for now I just want https://MeaganVisser.com to redirect to https://MeaganVisser.com/blog so people can see the posts. How do I do that? and why is nothing showing up for https://MeaganVisser.com/blog?

I’m totally lost.

Any help would be appreciated.
