My component is loading in author instance but not replicated in publish instance.
try deploying it via a package to the pub instance.
It would be nice to have more details about the issue you are facing in. However, there are a few things that you can do.
Hope that can help.
As braullio_soares mentioned, check if the replication agents are configured properly . If yes, just replicate one content and check if it is coming fine. If so then your component should also replicate fine. But as mentioned previously in the replies , could you please elaborate your issue
