When I click “publish” wordpress navigates to a blank page

When I am creating a new post:

-If I click “save and continue editing”, “save”, or “publish” it just loads a blank page. It still publishes or saves the page, but if I save I have to go reload it to continue editing.

– When I add a link it says this:
WordPress

Documentation — Support Forums
2.0.4 — 0.24 seconds

(Isn’t it supposed to go back to the add link page or something)

Anyway there are a lot of little things like that that do not seem to be working. I am just wondering if there is a way to fix it. My blog is, if that helps: https://www.prematureoptimism.com/blog/

Thanks in advance,
