@ntoamrkt – Sorry but I didn’t understand any of that, at least not in terms of how it relates to Popup Maker.
Can you define these as they pertain to Popup Maker
– Custom Box Settings
– Holding
If your using anything like Advanced Custom Fields to add content it won’t work without modifications. If it did you would likely complain that other content was added to your popups that you didn’t want. IE a lot of plugins filter page/post content adding things, 99% of our users don’t want all that extra stuff added to their popup content, so we had to do it different than posts & pages.
So the ACF info doesn’t get added to ours automatically.
