As with all frameworks, the Joomla! Framework keeps an active list of issues to be resolved. Anyone can report new issues, and here are a few guidelines:
Login to GitHub
The first step in reporting an issue is to verify your account with GitHub. Joomla! Framework uses GitHub for managing its repositories and a single sign-on with GitHub helps keep all information in a central location.
Check the Issue
Verify your issue is not unique to your specific installation. This helps to ensure that your issue is indeed one which needs to be addressed by any of the Framework developers. If you find your issue does appear to be unique you may still request for advice and input from the Framework Mailing List.
Post the Issue
After you've followed the above two steps the last step is to post the issue. Select the appropriate label and be sure to list clear directions related to your issue and how to replicate it. Your issue should contain as much detail as possible to make sure other developers are able to see the same issue you do.
