 We have upgraded the server on which XWiki runs, but we now get an error
 when we want to delete a page: 
First, could you tell us to what version you are upgrading?

  What could be the cause? Where should we start
looking? 
This looks like some error of upgrading the schema. Are you sure that you have enabled
data migration:
xwiki.store.migration=1
xwiki.store.migration.databases=all
Thanks
