I also use Indexmenu extensively and cannot do without it on my wiki at this point.
however I cannot seem to get to the extension page to do the update as suggested by schplurtz
I still get handed a blank page.
I use the "bootstrap theme" and I'm wondering if this is causing some of my issue as well?
I am also only seeing the main blank page with the titlebar but cannot click on anything.
I have two wikis that have the same plugins and can confirm both my wikis have the same issue after upgrading.
fortunately I host my own wiki's on a Synology NAS and I have a C2 backup subscription so I am able to restore my last good wiki folders per 2am 😉
looking at the forum it would seem it is best to stay away from Hogfather for the moment until the plugin providers catch up with compatibility.
Would be useful if Dokuwiki could start a list of know issues and warn users before allowing the upgrade to actually take place.......I used the update plugin and it does not warn about any issues or dependencies and just happilly upgrades your wiki which is subsequently broken after.
Not a huge issue for me, but I can see some poor souls that don't think about backing up before upgrading sitting in a nasty situation 🙂
Just to add my positive (not complaining above, just observations and suggestions 😉 ).....I absolutely love Dokuwiki and want to thank everyone involved for a great piece of work! @andi your wiki is just great!!
