On 19 May 2014, a relaunch took place for the so-called update to 'version 4'. In the course of this update there were both server-technical as well as data-legal issues, as private data was visible to other users for an indefinite period of time.[7] For 48 hours the site had only a very limited availability, resulting in multiple complaints on Facebook.[8] The biggest criticisms from users was the confusing new design. As a result, Transfermarkt.de publicly apologized for the incidents and issues that were caused during the relaunch.[9]
