"HTTP Event Collector" not available or missing from Data Inputs panel, "Settings > Data inputs"

This screenshot speaks the issue. Due to no Http Event collector I'm not able to create one.

This turned out that old dbx version sitting in the apps directory broke the UI. Even if it's disabled it still affects the Data input list in the GUI. Removing old dbx app fixed the issue.
