are you on the same domain? This settings only work on the same domain because of security restrictions browsers have.

also onload_show_element_only in combination with iframe_hide_elements does not make sense. 

on the same domain onload_show_element_only will remove all html around it. Most of the time it is not a good idea to remove all html around because then css will not fit anymore.

I want to set an iFrame to exactly one section "#section_1000027" which I have indicated in the shortcode, I also wants to prevent, that the Header and Footer "#section_1000000, #section_1000001" are displayed:

But additional to the correct section the header and the footer are displayed. What's wrong in my shortcode?

Thanks a lot for your support
