@matthias, I propose that topic is moved into a common cat, like Collaboration
. Nothing private about it. Now access is granted via the collaborators
group, which is again not private but it makes @winnieponcelet’s life difficult if he has to ask every time a moderator is appointed.
That was actually the problem. Moderators should have access to that category, as well. Done now. Means for @winnieponcelet, all your Biofabforum moderators will now be able to access this list. (And the list entries now mention as well on which platform users signed up. I guess you noticed that already.)
Since this (1) only affects one thread for you, (2) does not affect the same thread in incognito mode and (3) does not affect the same thread for me, I think this is “just” an issue with the browser cache. For example, your Internet connection could have been interrupted while that thread was loading last time, and now “half-loaded” images are used from cache.
If so, a double reload (in Chrome / Firefox: press F5 twice) should solve it. If not, you can search for how to make your browser forget about a site or even how to empty all of its cache for all sites.
