SiteOrigin Button bug

Hi,

When I’m in the editor part of a page and I click on an existing SiteOrigin Button, I have a white page that shows up full in the whole page with only the date showing (e.g. Mon, 03 Dec 2018 14:56:20 GMT)

I tried with both Chrome and Firefox and have the same problem (I use Windows 10).

If I create a new SiteOrigin Button, it shows up properly at the time of the creation, and as soon as I “Update” by page, I have the same problem.

If I reload the white page with the date, I fall back on the normal editing view.

There is no problem with SiteOrigin Editor, SiteOrigin Image and SiteOrigin Slider.

Same problem happens on all pages.

Any idea what I can do to sort this?

Thanks for your help!
