Page layout/style sheet problems after upgrading to Komento 2

I'm running Komento and EasyDiscuss on a Joomla 3.4.1 site with the latest version of JomSocial. After upgrading to Komento 2, last night, I suddenly have the following problem.

When I click on any of the JomSocial status update links on the Jomsocial news stream

see: http://awesomescreenshot.com/04f4yxq3e4

I get a page layout error (missing style sheet) when I click on the link. However, if I go directly to the article, by Joomla searching for it or locating it in the articles sections, the page is displayed corrrectly.

I suspect this might have something to do with the funny URL used in the JomSocial status update link (https://therebel.is/index.php?option=com_content&view=article&id=840841:bomb-run-israel&catid=157:books&Itemid=1148 instead of http://therebel.is/books/840841-bomb-run-israel)

Why does it switch to secure mode? For some reason that causes the layout error. If I change the URL to the non-secure version, the layout is okay. Going over a secure link is also undesirable for another reason. The page does not get cached then via the CDN service, taking longer to load.
