1) i have version 2.8.1. on server and after my upgrade (to 3.3.0) it falls down with error code with message that link to line 25 on header.php of my childtheme (1.0.0.)
2) i discovered that i am not able to add text/html row to header. It also falls in 2.8.1
Could you please disable all plugins that are not related to our theme, switch to the parent theme and provide us your admin access so we can check it?
