Yes, just checked and my mistake. If you have access to FTP in your server and want to fix by yourself, open applications/links/extensions/core/EditorLocations/Links.php and find:
public function canAttach( $member, $field )
{
return TRUE;
}
Change to:
public function canAttach( $member, $field )
{
return NULL;
}
I'll fix in next version.
