Troubleshooting

  1. “Node.js not found” Error
    Solution:
    Check if Node.js is installed by running: node –version

    curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash –
    sudo apt-get install -y nodejs

  2. “Permission denied” Error
    Solution:
    Fix file permissions by running: chmod +x /path/to/nsfw-check.js
    Adjust directory permissions using: chmod 755 /path/to/temp/directory

  3. “API key invalid” Error
    Solutions:
    Verify the API key is correct
    Check whether the API key has the required permissions
    Make sure billing is set up if the API requires it
    Check if you have exceeded any API usage limits

  4. “Model download failed” Error
    Solution:
    Clear the npm cache and reinstall dependencies by navigating to the plugin’s library folder and running the following steps:
    Go to the plugin lib directory
    Delete the node_modules folder and the package-lock.json file
    Reinstall dependencies using npm install

  5. “Memory limit exceeded” Error
    Solution:
    Increase the PHP memory limit by adding the following in wp-config.php:
    ini_set(‘memory_limit’, ‘512M’);

Debug Mode
Enable WordPress debug mode to see detailed error messages by adding these lines to wp-config.php:
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);

Performance Optimization

For High-Traffic Sites

  1. Use Cloud APIs instead of local processing
  2. Implement caching for repeated images
  3. Set appropriate thresholds to reduce false positives
  4. Monitor API usage and costs

For Privacy-Conscious Sites

  1. Use NSFW.js for local processing
  2. Disable logging if not needed
  3. Regular cleanup of temp files

Security Considerations

API Key Security

  • Store API keys securely
  • Use environment variables if possible
  • Regularly rotate API keys
  • Monitor API usage for anomalies

File Upload Security

  • Validate file types before processing
  • Set appropriate file size limits
  • Implement rate limiting for uploads
