Today, when I visited the website, it showed me 237 messages, I just read 2-3 message,

while clicking on one of the message, Screen was not updated, instead of the original message, i saw only blank at the right bottom frame. So I clicked on reload, It asked me a question and I clicked on Ok.
Then the screen was updated and it showed only 2 new messages !!!!

I again visited the main page, again logged in and checked on new messages..... But It was only showing me those 2 messages.

Is there a way, I can get those messages back ??
