Content of post not showing in blog nor previews, there on Visual and HTML view

For some reason this post is not showing when published, although all the content is there when I edit it. https://coworking.betagroup.be/ideas-to-improve-the-belgian-tech-entrepreneurship-ecosystem/

Title, author, publication date, categories and tags do appear.

Here’s the pastebin of the post’s html: https://wordpress.pastebin.ca/2252958

If you look at the source code of the page, the content is just not there.

I’ve tried cleaning the code of styles but the post content still does not show.

I already had a problem like that before linked to the use of bit.ly urls. There was one in this post (linking to the video) which I removed and changed for the video, but nothing changed.

Thanks for your help!
