Hello. I followed
https://www.dokuwiki.org/interwiki guide and shortcut for other wiki works fine. What does not work is interwiki image. I downloaded png file, scaled it in gimp to 16x16 exported as png, uploaded it to server, saved in the <root>/lib/images/interwiki/<shortcut>.png, cleaned cache. The image doesn't appear in the wiki. Take a look, in the bottom in the input section
https://wiki.denko.me/doku.php?id=linux:archlinux:encrypted_persistent_usb_arch_linux_installation. The place for the icon is just blank.
What should I do and in what program should I scale and save the image in order for this to work?
