Stuck with an X from a popup

Hi, maybe somebody has had the same issue. I played with embedding a Youtube video using UIKit Video Stack. After publishing it kept coming up with an error message in the browser so I deleted the stack. Now randomly a small ‘close’ X comes up on my page, I’m presuming it’s the remnants of an advertising popup from Youtube. My question is, how do I remove it? I’m a very basic user so a detailed how to find the culprit code would be ace, cheers in advance.

Hi @DaveE,

Do you have a link to the page where the small ‘close’ X is appearing so everybody can take a look?

Hi Dan,
It was here but randomly, I haven’t had it come up for a few days now, so may have been something cached in my browser. https://kutalombok.site/page/
Do you think that the cache could have caused it?

Cheers

Dave
