When I visit a spot and then return to the page I previously was, no নবীকৃত তথ্য appear on it. Is this normal?

I suspect that আপনি are using your browser navigation (back and অগ্রবর্তী buttons) to সরানো between pages you've visited. Depending on your browser, this will load a cached version of the page to save bandwidth (most browsers do this). So, if আপনি weren't doing this already), make sure to navigate between pages দ্বারা clicking on লিঙ্ক in the pages অথবা using the ফ্যানপপ খুঁজুন feature. This should prompt your browser to contact the server and reload the page, rather than লোড হচ্ছে a cached version. As an alternative, আপনি can force the browser to reload a page (in most Windows browsers this is done দ্বারা holding down the SHIFT key and clicking the browser "reload" button). One অথবা the other (or both) of these should address your problem. If neither does help, then it is a bug, and should be reported using the "contact us" link at the bottom of any page.
