Requested URL not found/ 404 error

Hi, I’m new to all this and now pretty frustrated.
Created WP site but when clicking on links on the homepage to other pages I get:
Not Found

The requested URL /uncategorized/hello-world/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

What am I missing?

Thanks

You might give us a link to the site. From the post above it’s hard to say what you are missing.

The domain attached to your account seems to be working now. If that’s not the one (logo…) then I would guess your .htaccess file isn’t working.
