CB Auto Actions renders inline streams. That means it doesn't include the core CB template CSS files. The intended purpose of the action was to render inside of other CB plugins, but this will be improved in CB Activity 4.0.0 where it'll always output its container CSS like CB Gallery does. To workaround this you need to surround your return with the following.
Code:
$return = '<div class="cb_template">' . implode( '', TRIGGER ) . '</div>';
You may need to load core CB template CSS just before that with the following API call.
Code:
outputCbTemplate();
2nd question: Which seperator do i have to use for the imploding of the trigger return array?
None. Use '' as the implode separator.
