# Debugging backend PHP issues

## Logs in UI

You can view recent backend PHP errors directly in the Maintenance > Logs section of the UI. This provides quick access to logs without needing terminal access.

## Accessing logs directly

Sometimes, the UI might not be accessible. In that case, you can access the logs directly inside the container.

### Step-by-step:

1. Open a shell into the container:

`bash docker exec -it netalertx /bin/sh`

1. Check the NGINX error log:

`bash cat /var/log/nginx/error.log`

1. Check the PHP application error log:

`bash cat /app/log/app.php_errors.log`

These logs will help identify syntax issues, fatal errors, or startup problems when the UI fails to load properly.
