My guess is that you have not yet set up permalinks.

You don’t happen to know how I am supposed to set them up to get it work correctly?

All your questions should be answered in the Using_Permalinks document, to which I linked above.

If you still have questions after reading that document, please tell us what you tried, and how it didn’t work.

Yes, I understand the basic idea of the permalink structure, and right now I’m using the recommended one (/%year%/%monthnum%/%day%/%postname%/). I understand how that makes the path to specific posts, but I don’t understand what happens to the path to pages.
In the navigation bar, the url to my pages are toobigtofitinhere.com/page, but the “real” url is, as you said, /index.php/page.
What do I change in my admin panel so the links work?

It looks like you have not correctly made your .htaccess file, as the links to your categories look like this:
https://blog.toobigtofitinhere.com/archives/%post_id%/school/
https://blog.toobigtofitinhere.com/archives/%post_id%/tv/

Do you have a .htaccess file in the root of your WordPress directory?

When creating a permalink structure at Options -> Permalinks, WordPress should automatically create rules for your pages, as well. Once you get the .htaccess file created, everything should “just work.” Please fix the .htaccess problem, and then let us know what other problems may exist.

Ah, that’s right. I hadn’t updated the .htaccess file! I forgot that I had to do that manually.
Everything seems to work now. ??

Thank you so much for all your help!
