The problem might be caused by another extension interfering with the Ezekia one.
Navigate to the chrome://extensions/ page. For every extension you have EXCEPT Ezekia, move the blue slider to turn it off.
Restart the browser and try the Ezekia extension again. If it now works, turn the other extensions back on one by one, testing Ezekia each time. When the Ezekia extension stops working, you will know which extension is causing the problem.
