Yes, after updating Popup Maker the issue was resolved! Thank you so much!
The problem is clearly not on their end. It’s an error happening within the Popup Maker dashboard, which other users have reported with other plugins beyond just ACF (my links above). If we cannot expect a fix from Popup Maker, that’s fine – just let me know, and I will find an alternative.
Hi @kimmyx , I tried disabling other plugins and no other plugin resolved the issue. I then disabled ACF Pro, and found that the problem was resolved. So I can confirm that the conflict is indeed with ACF Pro.
Like I said, I need to use ACF Pro. Is there a workaround that you could offer?
