Nevermind.. Missed this bug in the know bug list on Synology..... I'm sorry.
When I browse to the PMS (installed on Synology DSM 5.2, update 2), the language settings seems to refer to the general settings.
On the settings page (http://plexhost:32400/web/index.html#!/settings -> Server -> 'Show advanced' I choose for the button 'Talen' (Language in English). The language settings page doesn't show, instead PMS shows me the General settings page. Changing the adress in the adress bar from http://plexhost:32400/web/index.html#!/settings/server/xx/general to tp://plexhost:32400/web/index.html#!/settings/server/xx/language doesn't solve it. At the moment I'm unable to browse to the language settings tab at the settings page.
The attached image shows the page after I've clicked on 'language'. The word 'Talen' doesn't become yellow, every other option does color yellow after a mouseclick.
