SiteOrigin Widgets Bundle crash wp backoffice

Good morning,

I’ve installed Panoramic Theme Premium and when SiteOrigin Widgets Bundle is active, a blank page is shown in Pages Editor, Plugins administration page and Theme Customize page.
I’ve made many tests, disabling and removing the rest of plugins, and the problem is SiteOrigin Widgets Bundle plugin.

I had contacted with “Out The Box (theme suuport) and they redirect me to this forum to resolve.

Thanks in advance
