I'd like to say hi to members of the community.
I have a problem with the domain registration plugin.

When I try to activate it, I get the following message:

 

Oops!

For additional assistance, please reference the WHMCS TroubleShooting Guide »

Error: Class 'WHMCS\Module\Addon\domenytv\Installer' not found in /home2/admin/domains/hostline.pl/public_html/billing/modules/addons/domenytv/domenytv.php:51
Stack trace:
#0 /home2/admin/domains/hostline.pl/public_html/billing/admin/configaddonmods.php(0): domenytv_activate()
#1 {main}

 

The plug is said to be compatible with the latest WHMCS. I am using WHMCS version 8.2.1, PHP 7.4.23, server: openlightspeed on cloudlinux with directadmin.

I would be very grateful for your help
