Isotope Gallery don’t work on blog posts

I created a gallery with Isotope Gallery, but the gallery does not work on blog posts, only on pages. In the examples below, I used the same gallery for a test page and a test post, see that only works on the page.

Gallery Shortcode: [isotope_gallery id=”41″]

Is there any incompatibility with Isotope Gallery in posts?
