Thanks for your reply! However, the issue here is not the word HELLO, but that the next sentence “Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!
This entry was posted in Uncategorized on június 24, 2013.” is not translated by WordPress to Hungarian. Everything else in the site is! Even the date in the above quote is in Hungarian! So, the question is, from which file could this English sentence come from? If I know, I could edit it, and put in the correct translation myself.
