Prerequisites

• One page tree per country (“country branch”)
• Root of each country branch has the option “Use as Root Page” set
• Crosslinks between the country branches work. Perhaps you have to set config.typolinkCheckRootline = 1 and config.typolinkEnableLinksAcrossDomains = 1 in your TypoScript setup.
• If you have MountPages, try to set config.MP_disableTypolinkClosestMPvalue = 1 in your TypoScript setup.

Since version 4.0 you have to use the new page translation without the table “pages_language_overlay”!
