Hello @_kom__ ,
We need to debug these notices in the occurred hosts. We actually understand what sometimes it is impossible to you to give the administrative access to your website.
If it possible, just do some debug stuff what happening in line modules/cleantalk/src/EventSubscriber/BootSubscriber.php:176 (see the screenshot code.png) after the module updated.
This is the another way to fix the issue. Hope to your help!
Hello and thank you for delay!
We have added custom permission to manage CleanTalk settings.
Just apply a patch attached and grant selected user groups "Changing CleanTalk settings" permission.
Does this suit for you? Will waiting feedback from you.
