Beperkte functionaliteit na upgraden naar 5.20

Hallo,
Nu upgraden van 5.12 naar 5.20 heb ik ook alle modules geupgraded. Ook de database is aangepast.
Nu blijken op de bewerkingspagina van een node alleen de invulvensters en de onderste knoppen nog te werken.
Links zoals "Input format", "Expiration", "Authoring information" en "Publishing options" werken niet meer. Nochtans zit er meer informatie achter als ik de pagina kopieer en hier plak, zie maar:

Input format

Kan iemand mij helpen? Ligt het aan een module? Aan toegangsrechten?
Bedankt.
