Do not update/delete: Banner broadcast message test data
Do not update/delete: Notification broadcast message test data
Without internet access, the Update Check on the Help page shows a broken image:
I'd say 404'd image, but the Chrome Inspector shows (failed) Status on Network tab, and net::ERR_CONNECTION_TIMED_OUT on Console tab.
(failed)
net::ERR_CONNECTION_TIMED_OUT
Also make it pretty when Update Check fails.
