Pages shown are really old

for some reason when i log on some pages are really old and not updated

like the homepage has everything on it that happend yesterday(it still says i have 1 unread message and 51 total but i actually have 53)

some other pages do the same

the ones that work say that there was a new post on a thread. but when i go to that thread its not updated and doesnt show me the new post

its nothing i havent been able to get around as of yet

but it really could become a problem for me

dont know if anyone else has this problem...
