Hello, I would like to report a routing bug in SP Page Builder Pro.

Steps to reproduce: Environment: Joomla 5 or 6 (the issue exists on both).

Steps:

1. Install Joomla 5.4.5 with the Shaper Helix Ultimate template.
2. Set the homepage to a page built with SP Page Builder Pro (Page type).
3. Create a menu item of type "Category Blog" and add several articles to that category.

Open the site and navigate to that blog category menu item. For example: https://test5.my-joomla.ru/tests/test1 Where: tests = category alias test1 = article alias → Everything works as expected.

The issue: Now change the URL to remove the category part: https://test5.my-joomla.ru/test1

Expected result: HTTP 404 (Not Found).

Actual result: The SPPB routing intercepts the request, searches the database for an article with alias test1, and tries to display it. It fails, but instead of a 404, the page returns HTTP 200 OK and shows this message:

"You don't have permission to access this. Please contact a website administrator if this is incorrect."

Problem: The page returns HTTP 200, so it gets indexed by search engines. There is no redirect. This creates an unwanted duplicate page for every article.

Temporary workaround I found: In the file: /components/com_sppagebuilder/router.php

Right after the method:

private static function getCollectionItemIdFromSlug($slug)
{

I added:

return null;

This prevents SPPB routing from intercepting these URLs, and the pages no longer exist.

Request: Could you please look into this issue? A proper fix is needed so that SPPB does not handle these "empty" URLs and return HTTP 200. Currently, it creates unnecessary indexable pages.

Thank you.
