Hi Rikard,
I am facing the exact same issue after the upgrade. As per above instruction I went ahead and used the footer.php from the main theme and did customization again. Now the issue is that when I am logged in to back-end of wordpress and I check the site footer is coming properly but when I log out the footer goes back to a defautl which is not set by me. it shows interesting links- category- pages- arcive i 4 different columns
Please help
Ray
