Troubleshooting

You can often diagnose a problem with MultiBit Classic by looking at the Messages window by selecting the 'View | Messages' menu option.

For a more detailed description of what has happened with MultiBit Classic there is a log file to look at. This is stored in the log directory in your user data directory and is called multibit.log. Use a simple text viewer like Notepad or TextEdit to read it.

Where MultiBit Classic stores your data

MultiBit Classic stores user specific data such as logs and the default multibit.wallet in a "user data directory". This directory can be worked out as follows:

  1. Check the the very top of the "Messages" tab for a message like "The user data directory is '/Users/example/Library/Application Support/MultiBit'"
  2. Navigate to the MultiBit Classic installation directory and check for a file called "multibit.properties". If there is, use this directory as the user data directory. This is for backwards compatibility and for running everything from a USB drive.
  3. If none of these reveal the answer, use the technical approach given below.

Technical approach

This section is for technical users proficient with accessing environment variables. These are enclosed in "[]" such that [APPDATA] references the APPDATA environment variable.
