Troubleshooting

If You Encounter Issues

1. Enable Developer Mode

   • Open system/config.php
   • Change APP_STAGE from 'Live' to 'Dev'

   define('APP_STAGE', 'Dev');
   

   • This will display detailed error messages

2. Manual Database Schema Update If the automatic schema update fails:

   • Visit: your-domain/?ng=updating/schema
   • Or with URL rewrite enabled: your-domain/updating/schema
