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:
- 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!)
- Verify username: Make sure you're using your WordPress username, not your email address
- 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:
- Check user role: You need at least Editor role. Administrator is recommended.
- Verify capabilities: Your user must have the
publish_postscapability - 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:
- 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)
- ✓ Correct:
- Test REST API: Visit
https://yoursite.com/wp-jsonin your browser. You should see JSON data, not a 404 page. - Check .htaccess: Some server configurations block REST API access. Contact your host if needed.
- Plugin conflicts: Disable security plugins temporarily to test
500 Internal Server Error
What it means:
WordPress encountered a PHP error or plugin conflict.
Solutions:
- Check WordPress error logs: Look in
wp-content/debug.logif debugging is enabled - Increase PHP memory: Add to wp-config.php:
define('WP_MEMORY_LIMIT', '256M'); - Disable plugins: Temporarily disable security and optimization plugins
- 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:
- Check site speed: Visit your site. If it loads slowly, you may have performance issues
- Whitelist BlogFlux: If you have a firewall, whitelist BlogFlux's IP addresses
- Increase timeout: In BlogFlux, increase the connection timeout in blog connection settings
- 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:
- Verify SSL: Visit SSL Labs to test your certificate
