404 page does not work when SEF is enabled

[cjsmiff]

I am using Joomla 4.1.0 and have a problem with the error.php for 404 page, it redirects non existing urls to the home page. The issue occurs when enabling Joomla SEF URLs (yes .htaccess is enabled). I have tried using Joomla default template and error.php file but the problem persists. I have searched high and low for a solution and nothing I try works. I ended up here: viewtopic.php?f=816&t=991546 which may or may not be the same issue.

If you have a .htaccess file then You can force to load your 404 page by .htaccess file:

ErrorDocument 404 http://yourdomain.com/404.php
Put it on top of your .htaccess file

EDIT: Replace http://yourdomain.com/404.php with your Joomla 404 URL.

Let me know if it works or not.

Thanks

Hi, thank you but this is one of the many suggestions I have tried.

It happens with all of my 4.5+ installations, each with different plugins etc and templates. And it only happens when turning SEF on in global configuration.

I have exactly the same problem. Any news on this matter?

I could finally solve my problem in 2 steps:

1. I could specify the menu ID for the 404 redirect within the settings of my Joomla template (Gavick Hubs). For whatever reason, the ID was not correctly set this way. I had to change the error.php file manually.

2. 404 errors are not redirected to the defined error page until the website is online. 404 errors are automatically redirected to .../index.php when you're in offline mode and logged in as an administrator.
