Hi, long story short, line 1273 to 1240 of quick-chat.php states:
public function add_dashboard_widgets() {
if($this->user_status == 0)
wp_add_dashboard_widget('quick_chat_dashboard_widget', __('Quick Chat Admin\'s Lounge','quick-chat'), array($this, 'dashboard_widget'));
}
To make "Author" (and more privileged roles) to be able to chat convert this code into something like:
public function add_dashboard_widgets() {
if(current_user_can('edit_published_posts'))
wp_add_dashboard_widget('quick_chat_dashboard_widget', __('Quick Chat Admin\'s Lounge','quick-chat'), array($this, 'dashboard_widget'));
}
You can replace edit_published_posts with any capability from table here to make it more or less restrictive. I recommend placing 'edit_posts' for "Contributor" (and more privileged roles) and 'read' capability for "Subscriber" (and more privileged roles) but any role from table will work.
Good luck!
