Troubleshooting: WordPress Publishing Errors

Common WordPress Publishing Errors

This guide will help you diagnose and fix the most common errors when publishing to WordPress.

401 Unauthorized Error

What it means:

Your WordPress Application Password is invalid or incorrect.

Solutions:

1. Regenerate Application Password:
   • Log into WordPress admin
   • Go to Users → Profile
   • Scroll to Application Passwords section
   • Delete the old BlogFlux password
   • Create a new one
   • Copy it carefully (no extra spaces!)
2. Verify username: Make sure you're using your WordPress username, not your email address
3. Check for spaces: Application Passwords are typically shown with spaces for readability, but some sites require them without spaces

Test with curl:

curl -u username:application_password \
https://yoursite.com/wp-json/wp/v2/posts

If this returns posts data, your credentials work. If it returns 401, regenerate the password.

403 Forbidden Error

What it means:

Your WordPress user lacks permission to publish posts.

Solutions:

1. Check user role: You need at least Editor role. Administrator is recommended.
2. Verify capabilities: Your user must have the publish_posts capability
3. Check plugin restrictions: Some security plugins restrict API access

404 Not Found Error

What it means:

The WordPress site URL is incorrect or the REST API is disabled.

Solutions:

1. Verify URL format:
   • ✓ Correct: https://yourdomain.com (base URL only)
   • ✗ Wrong: https://yourdomain.com/wp-json (BlogFlux adds this automatically)
   • ✗ Wrong: https://yourdomain.com/ (trailing slash)
2. Test REST API: Visit https://yoursite.com/wp-json in your browser. You should see JSON data, not a 404 page.
3. Check .htaccess: Some server configurations block REST API access. Contact your host if needed.
4. Plugin conflicts: Disable security plugins temporarily to test

500 Internal Server Error

What it means:

WordPress encountered a PHP error or plugin conflict.

Solutions:

1. Check WordPress error logs: Look in wp-content/debug.log if debugging is enabled
2. Increase PHP memory: Add to wp-config.php: define('WP_MEMORY_LIMIT', '256M');
3. Disable plugins: Temporarily disable security and optimization plugins
4. Contact hosting: Your server may have resource limits or configuration issues

Connection Timeout

What it means:

Your WordPress site is too slow to respond, or a firewall is blocking the connection.

Solutions:

1. Check site speed: Visit your site. If it loads slowly, you may have performance issues
2. Whitelist BlogFlux: If you have a firewall, whitelist BlogFlux's IP addresses
3. Increase timeout: In BlogFlux, increase the connection timeout in blog connection settings
4. Optimize WordPress: Use caching plugins and optimize your database

SSL/HTTPS Issues

What it means:

Your SSL certificate is invalid, expired, or not properly configured.

Solutions:

1. Verify SSL: Visit SSL Labs to test your certificate
2. Update WordPress URL: Make sure both "WordPress Address" and "Site Address" in Settings → General use HTTPS
3. Force HTTPS: Add to wp-config.php: define('FORCE_SSL_ADMIN', true);
