Error: 0 Call to undefined function create_fuction() - Kazumi template

Hello

Website www.johannesvlerick.eu is not working anymore. You see an error message:

Error: 0 Call to undefined function create_fuction()

When I look into the inspectorwindow, the theme/template Kazumi is the causes the problem:

Warning: Trying to access array offset on value of type int in /customers/b/a/f/johannesvlerick.eu/httpd.www/templates/jp-kazumi/warp/src/Warp/Config/Repository.php on line 243

I've just updated to the latest php version, but I don't know if this will solve the problem.

Anyone who knows how I can fix this?

Thanks!

Janis

I've just updated to the latest php version,

Warp 7 is not kompatible with PHP 8!



I recomment to build up the site with Joomla 4.0.6,
and Astroid-Framework.
