-## Troubleshooting
-
-### Exceptions not being captured
-
-1. Verify PostHog is initialized:
-   ```ruby
-   Rails.console
-   > PostHog.initialized?
-   => true
-   ```
-
-2. Check that `auto_capture_exceptions` is set to `true`
-3. Check your excluded exceptions list
-4. Verify middleware is installed:
-   ```ruby
-   Rails.application.middleware
-   ```
-
-### User context not working
-
-1. Verify `current_user_method` matches your controller method
-2. Check that the user object responds to `posthog_distinct_id`, `distinct_id`, or `id`
-3. If using a custom identifier, set `PostHog::Rails.config.user_id_method = :your_method`
