Custom taxonomy still using query URL after fixing error

To address the issue of your custom taxonomy resource-category not displaying correctly even after fixing the custom post type and flushing permalinks, you can follow these steps:

  1. Double-check the Registration Code.
  2. Flush Permalinks Again: Go to Settings > Permalinks and click on Save Changes. This will flush the rewrite rules and update the permalinks.
  3. Clear Caches: Ensure that any caching plugins or server-side caching are cleared. Sometimes, changes are not immediately reflected due to cached data.
  4. Check for Conflicts: Deactivate all other plugins and switch to a default theme (like Twenty Twenty-One) to check if there is any conflict causing the issue. If the problem is resolved, reactivate your plugins one by one and switch back to your theme to identify the conflict.
