[Gelöst] Cornerstone - Translation is not displayed on front-end when using ATE or CTE

I'm using the X theme from Themeco, which should be compatible with WPML. And even though I've manually approved the translations to other languages (the main language is spanish, but we also want our website in catalan and english), when I change the language, only the navigation bar shows in another language, but the pages themselves still show up in spanish. Can you help me? the site is versteckter Link
