This project is hosting an Open Source project. By design the development process is open to be inspected. Issues should be related to the code itself and bugs which affect all deployments. Do not open issues relating only to a single deployment.

In general, it is useful if you follow Simon Tatham's guide for reporting bugs. At a minimum we would need:

• Browser and Operating System vendor and version numbers.
• A description of what you were trying to achieve.
• A description of what you did in order to achieve it.
• A description of what you expected to happen.
• A description of what actually happened.

If we don't have enough information to reproduce your issue, we will probably not be able to address it.
