Previously my first language - Hindi was not displayed in my posts. But to a great surprise, I have been seeing for a few days first language - Hindi on my posts automatically. I neither touched my control-panel nor edited any of my profile.
Are the administrators/moderators modified my profile details? Or
Some hackers break my password and using my id?
Nobody has edited your profile. Don't worry. We made a slight change to the forum yesterday, and what you are seeing on your posts is something that you will see on posts by all users. See the following announcement for more info:
Who edited my profile?
