SiteOrigin Slider doesn’t work no longer

Hi,

after an update to WordPress 4.4 the SiteOrigin Slider doesn’t work properly.
The Slider contains five images but it shows only the first image and then the slider disappears.

Anyone an idea?

Using WordPress 4.4 with Virtue Theme 3.4.3 (by Kadence) and a Child Theme, PageBuilder 2.2.2, SiteOrigin Widget Bundle 1.5.4

Thanks in advance for your help.
