I think that I can only see the PB content using Firefox.
Nevertheless, I found two other problems:
1. When I update content in PB and I save it, it does not save styles or links properly. As you can see in your picture, it only saves plain text. It means that if I want to make some change in the content, I have to insert all the styles and links again.
2. I don´t know where to access to the templates. Before, the access was at the top menu inside SPB and right now it only shows elements and category of elements.
Thanks
