Hi, I'm having this strange problem.

I'm tapping onto the DNN Modal function from inside the HTML editor to show a youtube video in a modal window, like this:

<a onclick="return dnnModal.show('/Home/VideoModules/tabid/355/mid/1050/Default.aspx?popUp=true',true,400,690,false)" href="/"><img alt="" src="/portals/0/Images/Home%20Page/main-slider-5.jpg" style="width: 100%;" /></a>

A while ago it was working just fine, bot a while ago, the popup stopped working when I'm browsing the site without being logged in, if I log in, it pops.

I checked permissions and they are fine (all users, unauthorised users have read rights).

Has anyone ever encounteres anithing like this? I'm using DNN 7.3.1

Thanks!
