Warning: Invalid argument supplied for foreach() in

This is the few lines surrounding line 487 in the file that is mentioned in the warning:

$cartItems=array();//ini array
$cartItemsCount=0;//count all items
$groupedItems=array();//ini array
$summary[‘items’]=array();//ini array
/**lets group items by id and sizes***/
foreach($session[‘items’] as $groupid=>$groupitems){
foreach($groupitems as $v){
$cartItemsCount++;
$cartItems[”.$groupid.”][]=array(‘sortname’=>$v[‘sortname’],’size’=>$v[‘size’],’sizename’=>$v[‘sizename’],’printname’=>$v[‘printname’],’price’=>$v[‘price’],’additionalinfo’=>$v[‘additionalinfo’]);

Is there something I need to fix in here?

although there’s a relatively easy way to fix this, it seems strange that this ever even occurs, so i am wondering if something else is amiss…

do you by any chance have a link so i can have a look at it ?

essentially it’s reasonably easy to fix the symptoms, but the cause might be somewhere else..

and another thing.
since it being working and not, did you move stuff to a different server or changed themes or something ?

Thank you.

No I did not move from domain or host or server. We were changing some of the images on the home page. I did disable the placeholder images on wp-pizza… pretty sure that was the only option changed.

i’m confused… whats the problem ?
all looks fine to me ..?!
i dont get any errors

Wow, I just went to the page on another browser and the warning is gone. Is there anything I need to do here, to be sure there isn’t an issue?
Thanks again

not really. has nothing to do with browsers. maybe some caching issue ?
really haven’t got a clue as i cannot see/reproduce the issue

ok, Thanks for all the help. I may bug you again if I see that error again.
Cheers,
Mike

I had to write another post to close the topic.
