Hey imothep85!
Here's an adjusted capx. I added a loader, so the iFrame only shows after its content is fully loaded.

Also, I checked the Le Soir site and it has, indeed, a http header called X-Frame-Options set to "sameorigin", which keeps it from being loaded in a frame that is not on the same site.
Note: do not add events to the layAssets layout. It's a eventless layout that has the purpose of storing stuff that will be created dynamically, since Construct 2 needs at least one instance to exist so it can load an object. Think of it as an asset repository.
Hope this helps. Cheers!
