Hi there,
Last week I installed Joomla 4.0.3 with Helix Ultimate 2.0.5 and SP Page Builder 3.7.15. I don't use any special template. I activated the system redirect plugin in Joomla and enabled the Search engine friendly url and use url rewrite. Now whenever someone enters a page that doesn't exist they won't get an 404 page but instead go to the homepage. How can I change that? Also because of that, the 301 redirects on my website are not working anymore since they get auto-redirected to my homepage. I haven't change my .htaccess or anything.
[EDIT]
I noticed that a clean installation is working fine. So 4.0.3 with the mentioned template/plugins.
As soon as I create a first page in SP Page Builder and make that the default menu item the 404 is not working anymore and the 301 redirects are not working anymore.
It looks like the bug fix 3.7.15 only solved part of the 301 issues and create a new one.

Detailed info about website etc. is visible to support only.
Hope someone can help me with this.
