Feeling like a huge idiot! I have 2 unraid servers. One on 6.6.6 one on 6.3.5. I found and installed User Scripts in the 6.6.6 but when I search CA for "User Scripts" in the 6.3.5 machine I get "No Matching Content Found" but if I search just "User" I get 21 results none of which are the right one. What gives?
I did manage to install it manually using the URL, someone tell me this is either very weird or very common.
