Not working on Custom Post Type

Hello. The plugin works ok for the normal post types and also for one custom that I created (I have 2 custom post types). Let’s say it works for custom post type A, but not for B.

I tried everything. From clicking many different settings to using a shortcode and widget.

[cresta-social-share] in a text widget
add_filter(‘widget_text’, ‘do_shortcode’); // in functions.php

I tried to use the shortcode directly in the theme with echo do_shortcode(“[cresta-social-share]”), but no success.

Also this doesn’t work:

if(function_exists(‘add_social_button_in_content’)) {
echo add_social_button_in_content();
}

The IF actually happens, but nothing shows up. The functions does nothing.
