+**Q:** The Nightly Demo isn't loading for me!
+
+**A:** Are you looking at the uncompiled build with an AdBlocker enabled?
+We're rolling out ad support which is triggering some ad blockers to block
+requests for some of our source files. This only affects the uncompiled build.
+Switch to the compiled build (add "build=compiled" to the url) or temporarily
+disable your ad blocker to see the nightly uncompiled mode.
+Please note that if you want to test our ad logic, you might have to disable
+the ad blocker in compiled mode as well.
