the same errors as on the git-annex site.
Update2: it seems this is specific to the HTTP/HTTPS switch. If I use HTTPS, things work fine, but not with plain HTTP. So I'm moving this to the branchable wiki, as I am not having that problem on other ikiwiki sites. Maybe the bug specific to ikiwiki is the lack of clarity in figuring out wth is going on here... See <http://www.branchable.com/bugs/login_failures_without_https>

+I've prepared a bootstrap branch based on
+<https://github.com/gsliepen/ikistrap>.
+
+Main impediment to merging it is jquery; bootstrap probably needs
+a newer version than the 1.6.2 included in ikiwiki and upgrading
+it would need testing the parts of ikiwiki that use jquery.
+
+It also needs to include bootstrap 4 in ikiwiki, rather than pulling
+it from the CDN, probably. Although depending on a debian package
+would be nicer, if bootstrap 4 got packaged in Debian.
+
+Note that the template changes are not entirely optimial, but I
+did them in a way that makes the diff pretty clear that nothing changes
+except when the bootstrap theme is enabled.
