Hi,

I tried to increase the PHP version of 2 different websites to 8.0. In both cases the desktop version is ok, but in the mobile versio one only receives an error page with the following messages

Fatal error
: Uncaught Error: Call to undefined function create_function() in /homepages/29/d113802304/htdocs/wp/wp-content/themes/inovado/framework/inc/widgets/custommenu.php:67

#5 /homepages/29/d113802304/htdocs/wp/index.php(17): require(‘/homepages/29/d…’)
#6 {main}
thrown in

What can be done to fix this?

Kind regards

Luisa
