Tagged: call_user_func(), warning
I’ve uploaded the Cookie Notice plugin on WordPress 3.4.2, in settings area there’s this warning
“Warning: call_user_func() [function.call-user-func]: First argument is expected to be a valid callback in /web/htdocs/www.francescocavuoto.it/home/wp-admin/includes/template.php on line 1119”
and so it doesn’t work – even if the settings are saved.
How can I fix it?
It doesn’t mean that the warning comes from CN?
But the best, far the best thing you can do is to update WordPress.
