After updating to beta11, I get this in my javascript console:

    You have to enable javascript in your browser to use an application built with Vaadin.

Looking at the bootstrap js file, I see that it expects to be able to parse the config string as a json string - but instead it gets HTML.

Any suggestions?

Hi,

You likely have an old version of vaadinBootstrap.js in your browser cache. Try cleaning it and see if it helps.

That was it, thanks.
