Error with wordpress

The error says it all (but if you’re not techy then it might not make much snese):

Fatal error: Uncaught Error: Call to undefined function create_function() in /customers/9/1/f/protouch-bilpleje.dk/httpd.www/wp-content/themes/servicemaster-1/framework/modules/widgets/sticky-sidebar/sticky-sidebar.php:25

There’s a call to an ‘undefined function’ that’s breaking the site. In this case, that function is create_function(). From what I’ve seen so far, I’d guess that you’ve recently upgraded the PHP version on your site? That function is removed in PHP version 8, so if your site is running on any PHP v.8 then you will get that error.

There’s two things that can be done. First, downgrade the PGP version to anything thats 7.x. That will “fix” it for now, until your hosting company forces an upgrade to version 8. Second, go back to the themes author and ask them to fix it and release a new version that doesn’t include that function call.
