I am having a problem with creating a custom 404 page.
I followed these instructions exactly: https://www.joomshaper.com/blog/create-a-custom-joomla-404-page-with-sp-page-builder
The page is created but 404 errors are redirecting to the home page . I have cleared all caches but it is still not working.
Please could someone take a look and see if they can spot what I am doing wrong?
