Houston, we have a problem! Tried this with two machines and three versions of the Avisio theme (your demo included) - in IE9 the index header and portfolio images don't load!! Big problem! Any urgent ideas?
On a separate issue, do you have a work round for the permalink problem post the 3.1 update. Only default WP permalinks (nasty) solve the issue on post pages.
Thanks in advance. First issue is more pressing.
