Bitnami packages and configures already existing applications. We can only offer support and help on basic and most frequent application configurations. Always based on the default configuration or on our guides.
Your question is related to the application itself or any third party tool, and probably someone with more experience and knowledge about that specific tool can help you better than we can.
We suggest you to post your question on the official support forums of the application so others can help you with your issue. Please find below the link to the official Redmine forum
Do not hesitate to ask any other question you may have.
