[Resuelto] the pages are not displayed correctly in the translations

Hello, we have installed your tool on the Camperbase.de website and had the website translated into four languages. Unfortunately, the pages are not displayed correctly in the translations (page name on website, header/slider and translation are not displayed) Systemic requirements are all present according to our programmer. The update of the WPML Multilingual CMS plug-in does not start either. We are under a lot of pressure from our customers, as a multilingual newsletter is to be sent out on Friday. We are therefore hoping for quick support. Many thanks and best regards
