PrestaShop 新分类链接指向错误类别问题排查求助

Hey there, let's dig into why your new category (ID 12) is redirecting to the old ID 5 category in PrestaShop 1.7.5.2. Since you haven’t modified any code, these are the most probable causes and fixes to check:

• Cached URL Rewrite Rules
  PrestaShop relies heavily on caching for URL generation, and stale cache is one of the most common culprits here.

  • Fix steps: Head to your backoffice, go to Advanced Parameters > Performance, then clear all caches (Smarty cache, cache directory, compiled templates). Next, navigate to SEO & URLs, ensure Friendly URL is enabled, and click Generate .htaccess file to refresh rewrite rules. Don’t forget to clear any server-side caching (like Redis, APC, or CDN cache) if you’re using it.

• Duplicate or Incorrect Slug in SEO Settings
  Even though your URL structure uses ID-CATEGORY_NAME, a misconfigured slug could cause a conflict.

  • Fix steps: Go to Catalog > Categories, edit your ID 12 category, switch to the SEO tab. Verify the Friendly URL field is set to 12-categorynew. Then check the ID 5 category’s SEO tab to confirm its slug is 5-categoryold. If the new category’s slug was accidentally set to match the old one, update it and clear cache afterward.

• Corrupted URL Rewrite Database Entries
  The ps_url_rewrite table in your database might have incorrect mappings linking the new category to the old one.

  • Fix steps: Access your database via phpMyAdmin, locate the ps_url_rewrite table. Search for entries where id_category = 12—check that id_object matches 12 and link_rewrite is 12-categorynew. Also, look for any entries where link_rewrite = 12-categorynew but id_category = 5; delete or correct those entries, then clear your store’s cache.

• Accidental Parent Category Misconfiguration
  While less likely with your ID-based URL structure, it’s worth checking if the new category was incorrectly set as a child of the old one, causing URL inheritance.

  • Fix steps: Edit the ID 12 category, go to the General tab, and verify the Parent category is set correctly (e.g., root category, not ID 5). Adjust if needed and save changes.

• Broken .htaccess Rules
  Sometimes the auto-generated .htaccess file can have outdated or incorrect rewrite rules, even if you didn’t edit it manually.

  • Fix steps: Go to SEO & URLs in your backoffice and click Generate .htaccess file to overwrite the existing one. If that doesn’t work, you can compare your current .htaccess with the official PrestaShop 1.7.5.2 template (from a fresh installation of the same version) to spot discrepancies.

If none of these fix the issue, check if you have any SEO or URL optimization modules installed—third-party plugins can sometimes interfere with default URL handling.
