I have a problem using Blue PageBuilder.
When I try to create nested columns (column in column), it is impossible to save the page. Nothing happens when I click on the "save" button.
When there's no nested columns on the layout, it saves just fine.
I looked up on the console of Firefox Web Development tools, and it seems to be a JS error.
Here is the error returned by the save button when there are some nested columns :
TypeError: data.content[index] is undefined plugin-design.js
An empty string has been transmitted to « getElementById() »
Well that's kind of a big disappointment. It also seems it's not possible either to create several independants sections in which you can put some columns.
Sorry, but that's not the kind of builder I would recommend, it's really not flexible.
