Custom Sidebars Pro with Calendarize It

We have an problem with Custom Sidebars Pro in combination with Calendarize It (https://codecanyon.net/item/calendarize-it-for-wordpress/2568439). At the Calendarize It page we get an javascript error:

ReferenceError: wpmUi is not defined
var modal = wpmUi._make_modal( ‘light’ );

Both plug-ins and WordPress are the latest version and I get this error with different browsers. When I disable Custom Sidebars Pro the error is gone.... there must be some conflict somewhere?

    Hi Johan,

    So sorry to hear the inconvenience you are having. As Calendarize It is a third party paid plugin, we don't have any access to it's code and architecture. So we can't actually tell what is conflicting.

    Is this possible for you to send us a copy of that plugin so we can try to regenerate the same issue on my local test site? I'll report to our developer as soon as I can regenerate this on my local test site.

    To send that plugin securely, can you upload that to any popular file sharing service site like Dropbox or Google Drive and send us a message with the download link through our secure contact form here: https://premium.wpmudev.org/contact/#i-have-a-different-question ?
