I'm using the sh404SEF custom error page on my site. In sh404SEF > Configuration > Error page > Basic Configuration, I have the 404 error handling option set to "Override Joomla 404 error page". Previously, this worked correctly and showed the custom error page content from the "Error page en_GB" tab.

Now, the error page is just giving a white screen. If I change the setting to "Use Joomla 404 error page", it correctly shows the default Joomla 404 page. How do I get the sh404SEF custom 404 page to display correctly again?

The sh404SEF component and my site's template have both been updated since I last saw it working, so not sure if either of those may be related to the issue.

Hi

1 - What are the exact and full versions of Joomla and sh404SEF that you use?

2 -

Now, the error page is just giving a white screen.

Go to Joomla configuration and set "Error reporting" to "Maximum". This should give you an actual error message.

3 - Switch to one of Joomla native templates such as Protostar temporarily and see if this happens also.

1) The versions are Joomla 3.8.5 and sh404SEF 4.13.2.3783

2) This is the error message it gives when error reporting is set to Maximum:

Warning: json_decode() expects parameter 1 to be string, array given in /home/xxxx/public_html/plugins/system/yootheme/yootheme.php on line 121

Fatal error: Cannot declare class Joomla\CMS\Document\Renderer\Html\ModulesRenderer, because the name is already in use in /home/xxxx/public_html/templates/yootheme/vendor/yootheme/theme/platforms/joomla-modules/src/ModulesRenderer.php on line 41

3) I tried switching to Protostar temporarily and the custom 404 page did show up.

Ah yes, this is a known bug in your Yootheme template.

You can update to the latest dev version, from the development versions download area. This template is not the only one doing this, so we made a workaround for it.

After updating to the latest development version (4.13.3.3797-dev), I'm still seeing the same error for the 404 pages.

I did try clearing my browser cache and clearing the cache in Joomla, but it didn't help.

Hi

As mentioned, this is a known issue in the template. Yes, it will probably only happens when sh404SEF is in use, but it is entirely caused by the template. I suggest you talk to YooTheme about this issue in their code.
If they were to say this only happens because of sh404SEF, please remind them that there is no problem with other templates, and specifically the Joomla native ones.

Best regards
