How to enable debugging

It is possible to get the apps to display or log more information that might help debug various issues.

Desktop application

• Add a file named "flags.txt" in the config directory (should be ~/.config/joplin-desktop or c:\Users\YOUR_NAME\.config\joplin-desktop) with the following content: --open-dev-tools --log-level debug
• Restart the application
• The development tools should now be opened. Click the "Console" tab
• Now repeat the action that was causing problem. The console might output warnings or errors - please add them to the GitHub issue. Also open log.txt in the config folder and if there is any error or warning, please also add them to the issue.

CLI application

• Start the app with joplin --log-level debug
• Check the log.txt as specified above for the desktop application and attach the log to the GitHub issue (or just the warnings/errors if any)

Mobile application

• In the options, enable Advanced Option
• Open the log in the top right hand corner menu and post a screenshot of any error/warning.
