Hi,
I’ve checked. There is only one version of jQuery installed. I had to install the Enable JQuery Migrate Helper plugin because your Popup Maker uses the version of jQuery that WordPress USED to ship. They’ve upgraded, but you haven’t. That got rid of one error. It was complaining about a function not existing until I downgraded jQuery.
You may want to look into upgrading your plugin to work with the latest WordPress jQuery version.
The other error I finally found to be a conflict with WP Tiles.
I deactivated that plugin and the Trigger etc settings now work.
