Here you will learn how you can adapt existing themes to working fine with actually versions.
In 0.10 release, all refer links from head.php (to js, css and icon files) moved back to the <head> section in main.php, to keep them independet from themes.
So please edit your head.php in /themes/yourtheme/views/layouts/ and make sure that there are only refer to files in your theme folder. (otherwise they are loaded twice and can't work properly)
