TYPO3 Core

I noted several problem with the versioning feature. :

1- I can't preview a page version :
when I click on the "eye" picto, an error occurs ( The requested page didn't have a proper connection to the tree-root! (Broken rootline))
2- I can't preview version of content :
When I click on the "eye" picto :
I have this link : index.php?id=17&ADMCMD_vPrev[tt_content%3A7]=8
but the content don't change in comparaison with the original.
3- I can't add the versioning element in the tree page menu, it's not in the default menu.
