I checked your gallery pages and it seems the new widget is not responsive it overflows past the page on my phone. You may be able to leverage the embed external site feature in Website Pages to continue using Lightwidget for your instagram gallery. I'll open a support ticket for you with more details.
Thanks Cris, yeah it looks pretty bad on mobile. I couldn't get Lightwidget to work at all anymore so used a new one, SnapWidget. They say the iFrame on the Decoside is not allowing it to responsively resize. I don't mind it not working on mobile properly though, it will do until V8
