Unfortunately I can't give you access to the Plesk interface, I only have my reseller account.
But if you tell me what exactly you need, I can check/set it up for you.

Alternatively, you can make an Akeea backup with the login to the backend and debug it in your local environment.

I just had to please you to delete your copy again after finishing.

kunzemedien Do you have FTP account? I need to access file manager.

line 209

if($context != 'com_content.article' || !$this->isT4()) return "";

Kindly check.
