Sumeer,Blog is a publish side component. So I used publisher instance.
Despite that it shouldnt matter where you are. Also we recommended you
to try the component at /content/community-components/en/journal.html,
did you try that ?. When you try at that path, we can isolate if some
other client lib is interfering or not. I have attached my crxde
screenshot. As you can see, I am using the custom component you
provided.
