Firstly I'd like to say it is a great plugin. Just coming across a few issues though.
I downloaded the plugin from your site (which for some reason downloads the older version 1.1.4). I then tried it out and it seemed to work fine, the only issue was that it didn't gather all the styles for some of the widgets.
I then updated the plugin to version 1.2.2 and got a few more issues.
When I Publish or Update a page it takes me to an unstyled page showing the content with odd characters. I then have to go to the page itself to see the update plus I have to return to dashboard -> pages -> page to start editing again.
The columns do not work any more. Instead everything becomes 100% and sits underneath each other.
On the plus side it picks up the styles for all widgets.
Any idea what is causing this?
I have tried this on 3 themes; Striking, MyStyle, TwentyTwelve.
