Hi. I had already tried this as I found this solution on another post.
It didn’t make any difference.
However, this is what PopupBuilder developers have said :
We have checked the screenshots and seems you have inserted the wromg shortcode.
Here is how it needs to look like:
[sg_popup id=”27″ event=”onLoad”][/sg_popup] – OnLoad popup
[sg_popup id=”27″ event=”click”]Click Me[/sg_popup] – OnClick Popup
where the Id=27 – is you popup ID
Which worked.
So maybe they have changed how their popup works?
