I have installed several languages, so I have the following question: let's say a member has set his language (at my forum) to "chinese". Now I am going to delete this language from my system. what happens when the user (who has set to read my forum in chinese) is logging-in into my website and the language "chinese" is not available anymore, as I deleted this language. Will the user then have my forum shown in the default language? Or will he get a blank screen?
