Updated to 4.0 and editing of old pages has broken

Question

I just updated to 4.0 and cant edit old pages. When I try to edit a page I can only see the header / title and if I press on enter I will get an error page with the following cause:

java.lang.UnsupportedOperationException: The body of this ContentEntityObject ('my page name') was 'BodyType:WIKI' but was expected to be 'BodyType:XHTML'
     at com.atlassian.confluence.core.ContentEntityObject.getBodyContent(ContentEntityObject.java:169)

Any ideas where I should try to change the body type?

Best regards,
Hannu / FIN
