I’m new to XWiki and am currently testing version 15.8. I setup the wiki to use the Flamingo Theme Application
and the charcoal color theme. Now many instructions refer to customizing the skin, however on my installation I have no such button on the admin page. I can only customize the color theme. Which causes me to fail to attach e. g. a favicon or setting appropriate view rights. Is this per design or is my installation broken?
