Hi,

I just upgraded to V7, without touching the content.

Besides that the upload is incredibly slow (see other topic), I have some compatibility issues :

- some page do not preview, where in V6 the preview worked fine
  - pages that use FlickrCMS gallery (Flickrgram)
  - pages that use FormLoom3

the message “the page couldn’t be found … something went wrong”

The publication itself seems to be OK.
