Good news! The theme, plugins, demo content etc. are fully working on my server.
So the problem with bbpress and languages must be on the client side. ¿?
I’ll let you know if I get an idea of what’s going on there.
Also the language issue is resolved.
I’ve borrowed a couple of images from your live demo, just for a few of days, is that okey?
(a background for the revolution and the iMac image)
Maybe the main problem is on the client server, not in the theme/plugins.
I`m sorry for that… and thanks for the help!!
