Session start error in IE7?

[Newsgroup_User]

I have a page -

http://76.12.89.239/s_product-detail.php?ItemID=5&ItemSKU=01015

that contains the following on lines 8-12 -

<?php

if (!$_SESSION) { session_start(); }

?>

Why is that throwing an error?

Notice: A session had already been started - ignoring session_start() in
/vservers/squarewheeli/htdocs/s_product-detail.php on line 10

But it shouldn't be necessary. Obviously you're calling session_start()
multiple times, which should be fixed.

i thought i was having the same problem but then i checked what david wrote and that is exactly what i already have but this is the error i am getting on my homepage:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/gradsrus/public_html/index.php:2) in /home/gradsrus/public_html/index.php on line 6

any idea?

[Newsgroup_User]

Yes. In your case, you have already sent output to the screen and that's
why you are getting the headers already sent message. Search here for
"headers already sent" to read more.

It may be as simple as just moving a line or two to a different location.

i looked up what you mentioned and it only came up with three, one seemed to be on the same lines but didnt do the trick. what would i need to move around? or what do you think would fix it and/or a link i could go to?
