Trouble-shooting

On rare occasions, the Portfolio Performance app may malfunction or crash. Under the Help menu, three key options can assist in such cases.

Show Error Log

Each time the app starts, it generates a log file. You can view this log from within the application via Help > Show Error Log. Double-clicking a message displays the full entry. If no error occurred, the log will be minimal:

Figure 1. Log after successful start-up

When errors occur, they are listed sequentially:

Double-clicking an error entry opens more detailed information:

If the portfolio can still be opened, you should correct the historical price source for the affected security. If not, open the XML file in a text editor and manually remove the faulty data source.

You can copy the log text to the clipboard, for example when asking for help in the forum, or save it to a file.

Save Error Log

The log file is automatically saved in your user directory. Its default location depends on your operating system:

  • Windows:
    C:\Users\Your-name\AppData\Local\PortfolioPerformance\workspace\.metadata\

  • macOS:
    /Users/Your-name/Library/Application Support/name.abuchen.portfolio.ui/workspace/.metadata/

  • Linux:
    /home/Your-name/.portfolio-performance/workspace/.metadata/

To export the current log to a .log file, use the command Help > Save Error Log.

This version contains more technical details than the in-app error window:

When reporting issues on GitHub, include this log file. Avoid uploading portfolios that contain sensitive data.

Debug: Reset UI

The Help > Debug: Reset UI option opens a dialog. After confirming, restart the application:

Figure 5. Successful reset confirmation

Resetting the UI does not affect:

  • Created views
  • Custom reporting periods
  • Recent Files list

It does reset:

  • Window size and position
  • Visibility/layout of panes
  • Open files (not reopened on restart)

Use Reset UI as a minimal-impact first step when troubleshooting UI issues.

Update Error

If the installation is corrupted or files are missing, automatic updates may fail. In such cases, an error message will appear:

The recommended solution is to delete and reinstall the application.
