Not working with VisualComposer

I am using Bakery VisualComposer to create websites and when I add a post-masonry-grid (all post having the proper wp-post-modal css class) then when I click a post the popup opens well but in the next second it opens the post in the same window. Almost like it is working but is also unable to stop the link from sending me to the post page. I am working on a website that is not released yet and the only way to show you is to give you access. How can I do that privately? I am making free websites for free and volunteer projects, if that matters 🙂 – and thank you for your work!
