Will you please take underneath change of the stat.php in the next update 2.4 ??
This to get bubbamon working as normal, now we have to do that manually every time we update

Open /usr/share/web-admin/admin/controllers/stat.php in your preferred editor.
function stat(){
parent::Controller();
require_once(APPPATH."/legacy/defines.php");
require_once(ADMINFUNCS);
if(!($this->uri->segment(2) == 'index' && $this->uri->segment(3) == 'json'))
{
$this->Auth_model->enforce_policy('web_admin','administer', 'admin');
$this->Auth_model->EnforceAuth('web_admin');
}
load_lang("bubba",THEME.'/i18n/'.LANGUAGE);
Thanks in advance,
puma
