HI,

I’m having the same problem but with the MultiHost theme. It works fine up to Wordpress version 4.4.2, but with 4.5 and 4.5.1 the page builder doesn’t work. I can see thee Graphic and HTML buttons, can’t see any text I’ve created before. Switching between the Graphic and HTML button I get a javascript error in the Console:

Uncaught TypeError: Cannot read property ‘canvas’ of undefined

I have installed again the whole Worpdress, the theme, activated only the necessary pugins, nothing works.

Please help me, my client is a little bit nervous 🙂

Thanks,
