Troubleshooting

Google Drive authentication fails

• Verify OAuth credentials are correct
• Check redirect URI matches exactly
• Ensure Google Drive API is enabled
• Check for HTTPS requirement in production

Posts scan doesn't complete

• Check PHP memory limit
• Reduce batch size
• Check for JavaScript errors in console
• Verify user has manage_options capability

Build fails

• Run npm install and composer install
• Check Node.js version (12+ required)
• Clear node_modules and reinstall
• Check for disk space

Support

For issues or questions:

1. Check documentation files
2. Review inline code comments
3. Run unit tests to verify functionality
4. Check WordPress debug.log
