@PythonicNinja I can't replicate this are you able to give me some details on when this occurs e.g. on app start, on panel load? Also can I get the output from pip freeze?

[djsutho]

I'm looking to close this, @PythonicNinja do you have anything to add?

@djsutho sorry for delay from my side, I wasn't aware of your response year ago.

It was related to my settings.py which wasn't valid.

Long time ago but It seems that I still have good settings.py if anyone has same problem:

    INSTALLED_APPS += [
        'debug_toolbar',
    ]

    MIDDLEWARE = [
                     'debug_toolbar.middleware.DebugToolbarMiddleware',
                 ] + MIDDLEWARE

    DEBUG_TOOLBAR_PANELS = [
        'ddt_request_history.panels.request_history.RequestHistoryPanel',  # Here it is
        'debug_toolbar.panels.versions.VersionsPanel',
        'debug_toolbar.panels.timer.TimerPanel',
        'debug_toolbar.panels.settings.SettingsPanel',
        'debug_toolbar.panels.headers.HeadersPanel',
        'debug_toolbar.panels.request.RequestPanel',
        'debug_toolbar.panels.sql.SQLPanel',
        'debug_toolbar.panels.staticfiles.StaticFilesPanel',

        'debug_toolbar.panels.logging.LoggingPanel',
        'debug_toolbar.panels.redirects.RedirectsPanel',
    ]
    DEBUG_TOOLBAR_CONFIG = {
        # only required for debug_toolbar versions below 1.8
        'SHOW_TOOLBAR_CALLBACK': 'ddt_request_history.panels.request_history.allow_ajax',
    }
