Comments.Text: Check in your browser (*Inspect Element*) whether any `.js` resources are unable to be loaded (maybe `40x` responses for some files, look for red in *Network* tab) or you see any javascript errors (look for red in *Console* tab). Update question with any additional details you can provide. It's worthwhile describing the actual problem you're seeing (a blank screen? a page full of error messages? ?)
