no-cache for the login page is normal as well as for any page when logged in (we only cache for guests).Could it be because my board is private and this is only the login page?
I'm actually seeing this for every page I inspect too on my forum.
That is concerning, are you logged out and visiting the forum as a guest (perhaps try incognito)? I tried clicking around the site in your signature and was able to get a cache hit on the pages I visited. If it is a different site that is affected please private message me and we can look into it further.
