The workaround is to disable Adblock or Adblock extensions from the browser. If disabling the extensions at the browser-level is not feasible, then exclude the AppDynamics Controller site from these extensions/add-ons.
See How do I disable AdBlock in Chrome? for more information on how to enable the workaround.
The hotfix 4.5.2.x is not released yet.
