I decided to update SilverStripe to 2.4, hoping that would solve my problems. But I ended up with no Widget Area anymore in the CMS.

Update: Widget area is present but same error message

"Hi,

the only matter with this widget : it works only only in valid HTML and XHTML 1.0 documents, pages sent as text/html, not text/html. 'cause im using a script for embedding Adobe Flash content. So u have to remove this line "<?xml version="1.0" encoding="UTF-8"?>" from you're template page.ss.

It does work under IE without any change.

a new link for dowloading the widget : http://www.box.net/shared/azu0gmkz4e
