This is the first time I have used Silverstripe or PHP. I have Silverstripe installed on my local machine.
I am getting the following error message when I try to add a new member to either my Forum or administrator security groups:
[User Error] Object::__call() Method 'addtogroup' not found in class 'Form'
POST /silverstripe/admin/security/EditForm
Line 133 in C:\wamp\www\silverstripe\sapphire\core\Object.php.
In addition, the "Add Member" button at the bottom of the page does not work.
Has anyone seen this before or have any ideas?
Thanks.
