The theme is called “Michell” and on their official page on theme forest there is written that support is not available anymore..

Yes, I am in deep shit.

Ok, the conflict is because of my theme.
(if I change to other default wp theme the plugin works correctly).

Following your guide I already tried to set up the “skip_loop” option, but it still didn’t work.
Then I check if I have the php call into the footer and I have it correctly.
Next step is to check if my theme (which is “premium”) supports custom post type.

How can I check this?

Thanks for help
