 * Hello,
 * I have updated wordpress on a site i am working on, and have had to install BP
   Classic to resolve this issue, as one of my pages runs into a critical error.
   The line in the error log shows as:
 * Got error ‘PHP message: PHP Fatal error: Uncaught Error: Call to undefined function
   youzify_get_activity_page_class() in /var/www/vhosts/realmhub.co.uk/httpdocs/
   wp-content/plugins/youzify/includes/public/templates/activity/index.php:19
 * Any Fixes for this?

 * Hello [@runtyb](https://wordpress.org/support/users/runtyb/),
 * Please update your Youzify PRO version to the newest version (3.4.3). We released
   it yesterday. And then, make sure you disable BP Classic as in the newest version,
   no longer need that plugin. And then see if the issue solved or not.
 * Best Regards, KaineLabs Team.
