It may also be useful to provide the debugging output from the Troubleshooting page, sometimes even multiple examples (e.g. a working one and one where the issue comes up). Please use some service like Pastebin or GitHub Gist to post your logs and keep the thread clean and readable. Make sure to describe the exact steps you took when producing it.
