HTTP ERROR 500 via remote management in Cerber.Hub

Hi there!

I have a problem with remote control of websites through Cerber.Hub. When I try to view a “managed” website from the “manager” side, I get such an error:

Invalid response from the remote website
HTTP ERROR 500 The remote website (web server) is unable to proceed due to a fatal software (PHP) error. Check the server error log on the managed website.

I checked the debugger on the “managed” website, and it turns out the issue is with the file cerber-common.php and the function wp_is_auto_update_enabled_for_type(). Full logs below.

HP Fatal error: Uncaught Error: Call to undefined function wp_is_auto_update_enabled_for_type() in /home/xxxxxxxxxx/domains/yyyyyyyyyyy/public_html/wp-content/plugins/wp-cerber/cerber-common.php:664

thrown in /home/xxxxxxxxxx/domains/yyyyyyyyyyy/public_html/wp-content/plugins/wp-cerber/cerber-common.php on line 664

Disabling the option “Automatically update WP Cerber (Automatically install new versions of WP Cerber when they are available)” in WP Cerber on the “managed” website resolves the issue, but it also disables automatic updates. I have the latest version 9.5.6.

I will be grateful if you fix the issue quickly
Thanks
