If you’ve recently changed the permalinks on your WordPress site and now find that some links are no longer working, you’re not alone. This issue is more common than you might think and can arise from a variety of reasons. This comprehensive guide will explore why WordPress changed permalinks now links don’t work and offer practical solutions to get everything back in order
What Are Permalinks and Why Are They Important?
Permalinks are the permanent URLs used for your pages, posts, categories, and tags on WordPress. A clean, well-structured permalink is essential for SEO and user navigation. When your links aren’t working after a permalink change, it can disrupt user experience and SEO rankings.
Why Links Break After Changing Permalinks
- URL Structure Conflicts Changing your permalink structure often leads to broken links. WordPress generates URLs based on the new structure, but if you don’t adjust the internal links or use redirects, those old URLs might lead to 404 pages.
- Caching Issues Caching plugins or server-side caches might be storing the old URLs. As a result, even after you’ve changed your permalinks, users may still be seeing cached versions of your pages, leading to broken links.
- Missing Redirects When permalinks are altered, WordPress doesn’t automatically create redirects for the old URLs. This can cause pages that previously existed under one URL to become inaccessible.
- Database Corruption In some cases, database errors can prevent WordPress from saving the new permalink structure correctly, causing certain links to fail.
- Plugin Conflicts Some plugins that handle URL structures, such as SEO plugins or custom post type plugins, may not adjust correctly after a permalink change. This can cause conflicts and broken links.
- Server Rewrite Rules Your .htaccess file or server rewrite rules may not have updated correctly after the permalink change. This can cause URLs to break, particularly if you’re using a custom permalink structure.
Step-by-Step Solutions to Fix Broken Links After Changing Permalinks
1. Re-Save Permalink Settings
One of the simplest ways to fix broken links after changing permalinks is to go to Settings > Permalinks and click “Save Changes” again. This forces WordPress to refresh its permalink structure and rewrite the .htaccess file if needed.
2. Clear Caches
Caching plugins like W3 Total Cache or WP Super Cache might store old permalink data. Clear both the browser cache and any server-side caches. Additionally, if you’re using a Content Delivery Network (CDN) like Cloudflare, clear the cache there as well.
3. Implement Redirects
Use a redirection plugin like Redirection or Simple 301 Redirects to set up 301 redirects from the old URLs to the new ones. This ensures that visitors and search engines are sent to the correct page.
4. Check .htaccess or Nginx Configuration
If you’re on Apache, your .htaccess file may not have updated correctly. Access your website’s root directory via FTP and check the file. It should contain the default WordPress rules:
If you’re using Nginx, check your nginx.conf or nginx.conf.local and ensure the rewrite rules are set correctly.
5. Check for Plugin Conflicts
Deactivate all plugins and check if the permalinks work. If the issue is resolved, reactivate each plugin one by one to identify the one causing the problem. Often, SEO plugins or those handling custom post types might need to be reconfigured after a permalink change.
6. Repair the Database
Corrupt database entries can prevent permalinks from working correctly. You can repair the database using the WP-Optimize plugin or by accessing phpMyAdmin and running a repair command on the database tables.
7. Update Internal Links
If you’ve changed your permalink structure, it’s important to update the internal links in your content to reflect the new URLs. Manually search for and update any broken internal links, or use a plugin like Search & Replace to update URLs across the entire site.
Best Practices to Avoid Link Breaks When Changing Permalinks
- Plan Before Changing Permalinks Before making changes to the permalink structure, ensure you have a clear plan. This includes understanding the SEO impact and setting up necessary redirects.
- Backup Your Site Always create a backup of your website before making significant changes, including permalink adjustments. This ensures you can restore your site in case something goes wrong.
- Use a Staging Site If possible, test the permalink change on a staging site first. This will allow you to spot any issues before implementing the change on your live site.
- Use SEO-Friendly Permalink Structures Choose a permalink structure that is SEO-friendly and easy to understand. The default structure, “Post Name,” is often the best choice for most websites as it includes relevant keywords and is user-friendly.
- Monitor for Broken Links After making changes to permalinks, continuously monitor your website for broken links using tools like Google Search Console or Broken Link Checker.
Conclusion
When you change permalinks on your WordPress site, you may encounter issues where links don’t work or lead to 404 errors. These issues are typically caused by caching problems, missing redirects, or conflicts with plugins and server settings. By following the steps outlined in this guide, you can resolve these issues and prevent future permalink problems.
Always plan your permalink structure carefully, create backups before making changes, and monitor your site for broken links to ensure a smooth user experience and avoid SEO penalties.
