Shortcodes issue, downgrade to which version of PopupMaker ?

Hi,

Not sure you’ve seen my question on our previous exchange (here : https://www.ads-software.com/support/topic/shortcodes-not-working-anymore-2/ ).

If the shorcode issue is at an impass, would a downgrade of Popup Maker resolve the issue in the meantime ? (it used to work fine). If yes, to which version of Popup Maker should I do the downgrade ?

Thanks in advance for your help
