Attempted to call function "_menu_site_is_offline" from namespace "Ekino\Bundle\DrupalBundle\Drupal"

[zenmedia]

Hi,

I am currently upgrading our production environment from php 5.6 to php 7.0, and while our development server is running php 7.0.9 our live server keeps returning 'Attempted to call function "_menu_site_is_offline" from namespace "Ekino\Bundle\DrupalBundle\Drupal"' (Line 351).

There are no changes in code between the two versions of php, and the function _menu_site_is_offline still exists within the drupal includes folder.

Do you know what could cause this?

Very old issue but i have the same problem, and resolve it by upgrading drupal.
I think the error occured from this warning
