Pugin don't work to vb 4.0.4

[Asterix_ita]

Hello

I can not understand what has changed during the transition from VB 4.0.3 to VB 4.0.4
I created a plugin that inserted a new template at the end of postbit, all worked in 4.0.3 to 4.0.4 does not work

variables are recorded through this code

 if ($ctads['ok'] && $ctads['template'] == 0)
                {
                    $templater = vB_Template::create('postbit_ads_ct_2th');
                    $templater->register('post', $post);
                    $templater->register('ctads', $ctads);
                    $template_hook['postbit_end'] .= $templater->render();  
                }
                if ($ctads['ok'] && $ctads['template'] == 1)
                {
                $templater = vB_Template::create('postbit_legacy_ads_ct_2th');
                    $templater->register('post', $post);
                    $templater->register('ctads', $ctads);
                    $template_hook['postbit_end'] .= $templater->render(); 
                }

mi potete dare un aiutino, vedo che altri plugin non funzionano bene
