Fixed Group Forum Tree Server Error

[Freelancer]

When I open "/admin.php?nodes/groups", the page is blank except for this text:

An exception occurred: Invalid argument supplied for foreach() in /var/www/clients/client180/web812/web/library/NodesAsTabs/ViewAdmin/Node/List.php on line 15

XenForo_Application::handlePhpError() in NodesAsTabs/ViewAdmin/Node/List.php at line 15
NodesAsTabs_ViewAdmin_Node_List->renderHtml() in XenForo/ViewRenderer/Abstract.php at line 227
XenForo_ViewRenderer_Abstract->renderViewObject() in XenForo/ViewRenderer/HtmlAdmin.php at line 78
XenForo_ViewRenderer_HtmlAdmin->renderView() in XenForo/FrontController.php at line 607
XenForo_FrontController->renderView() in XenForo/FrontController.php at line 158
XenForo_FrontController->run() in /var/www/clients/client180/web812/web/admin.php at line 13

The Server Error Log shows:

Request State
array(3) {
  ["url"] => string(54) "https://www.xxxxxxxxxxxxxx.com/admin.php?nodes/groups"
  ["_GET"] => array(1) {
    ["nodes/groups"] => string(0) ""
  }
  ["_POST"] => array(0) {
  }
}

It's a conflict with the add-on "Nodes As Tabs"...
