not saying this is the answer.....but it might be......sometimes web browsers store and load old page info so it loads quicker.....try posting something then when you go on the page to check on it......hold shift, then click the Refresh/Reload button on your browser...this will do a full page refresh.....

if that works it has something to do with your browser settings.....i think it'd be the stored cookies....... let me know if that works........and if it does tell me the web browser you use and i'll tell ya how to fix it without haveing to hit shift+refresh all the time
