headers already sent when changing page
i have read around with the headers already sent error being white space etc.
however what i am finding is that say i am logged in and i am in the details page of the product. if i leave it for an hour or so then come back and click on results i get the white page with headers already sent error.
the only way around it is pressing back then loggin out and loggin in again.
has anyone in the community encountered this before with security assist and if so is there a way to resolve?
