WordPress update broke ssl

My hoster has updated my WordPress installation to the latest version (and broke it for several days). What they also did was disable my option to set the site address and wordpress address to https rather than http. So, now even though the site is still available through https://blog.dummzeuch.de it now longer automatically forces https connections. Thanks a lot. 🙁

What’s even worse: It reverses to plain http sometimes for no reason I can determine. e.g. I have been writing this post through http because I didn’t notice that until now. Thanks even more. :-((
