Popup doesn’t show after migration from old plugin

Hi,

I’ve migrated my popup (only using one) from the old plugin but it doesn’t work anymore. I’ve done the following:

1. Installed new plugin and imported popup from old plugin
2. Deleted old plugin
3. Checked settings of migrated popup, content and appearance looked fine
4. Display rules were correct too (https://imgur.com/aP5UZVx)
5. Added additional class triggering and used custom class ‘open-book-popup’ since
you mentioned that these have changed anyway during migration (https://imgur.com/RgjEi9q)
5. Opened menu settings and edited menu item (changed trigger class from old to ‘open-book-popup’) that should show popup when clicked (https://imgur.com/IKs9jt8)
6. Activated the popup
7. Deleted cache (I’m using WP Fastest Cache)

Unfortunately the popup neither shows while on the german homepage and scrolling down nor when I click the previoulsy mentioned menu item.

What am I doing wrong? Help is gladly appreciated.

With the old plugin, it worked flawlessly.
