An error of type E_ERROR was caused in line 17

Hi,

One of the websites that we manage has just reported the following error:

Error message: Uncaught Error: Call to undefined function SEOPress\Services\Options\get_network() in /var/www/clientswebsite.ie/htdocs/wp-content/plugins/wp-seopress/src/Services/Options/ToggleOption.php:17?

I have logged in and updated the plugin (free + Pro) to the latest version. I could see no error messages when in the back end. Is there any fix for this?

Thanks,
Michel.
