Ok guys,
I got a damn serious problem at the moment.
I tried something else so what I did was adding this code to the plugin:
PHP Code:
$templater = vB_Template::create('content_slider');
$template_hook['cms_content_slider'] = print_output($templater->render());
After that my website crashed....
The $content_slider template was successfully loaded and it is visible on a nice white blank page ...
the admincp also doesnt work anymore, because there is just a white page.
What I did after was logging into my phpmyadmin, table

lugins
fetch the one with my plugin and changed the php code, as well as i set activated to 0.
Still blank........
Anykind of help would be apprechiated a lot!
Vb4.0.3
Debug Mod on
//EDIT
DB Backup saved my a** however, I am really interested what that problem caused
