@lithia – Sorry to hear your having trouble with the latest update. Happy to help.
Can you elaborate in more detail how you came to that conclusion, for instance I assume you went to All Popups and found none? Or do they simply not work on the front end anymore and had to be modified manually?
That said I (the developer) am having a hard time with the idea that data was deleted somehow. To be clear we have a mandatory, but manually started, upgrade routine notice in the admin that changes data, but doesn’t in any way delete items from the post table where popups are stored. Explicitly it takes 4-6 post_meta keys and merges them into one to save space & make it more efficient.
Have you seen this notice and processed the upgrade? With 20 popups it would have taken a minute or 2 and been a noticeable experience. If not it still shouldn’t have removed popups from your admin.
Now to be blunt, if the popups are both deleted and removed from trash, I can say there is no code in our plugin to do such a task. IE we don’t even offer a delete popup option or function directly in our code. It is handled by wordpress post_type functions. So if that is in fact the case I’m not sure we can be of any help honestly, because they would both be gone already & it likely means that they were deleted manually or that there is some other plugin/code on the site that deleted them for some reason or another. The only thing that legitametely comes to mind would be a Database cleaning utility that deletes content it deems unused/unattached.
Look forward to hearing more details of your experience thus far to help track this down.
