I just installed it and the images were showing up for the install. When it finished the install the images disappeared and that was that. I tried changing the permissions from 700 on the folders to 770 as it says here
dokuwiki.org/install:permissions. I tried reinstalling the will a couple times after deleting everything. Still nothing. I logged on different computers, phones, iPad, Android. It's all no good. Kind of confused. I have an 18 page PDF with all the phpinfo so that's a thing.
