David Thomas Baker » PHP » PrestaShop | Not Working - Cannot login in Internet Explorer

Recently installed PrestaShop on a clients website - very nice and easy to use / administer shopping cart.

However when testing in IE 6 and 7 I realised nothing really worked, logging in, adding products to cart, creating accounts, nothing... Quite dissapointed and having already spent a long time configuring the shopping cart I decided to fix the problem rather than find a new cart product.

PrestaShop uses encrypted cookies to store all information rather than normal PHP sessions. Eventually figured out that Internet Explorer was constantly trying to re-create new cookies on every page load. So the problem was Internet Explorer could not save the cookies that PrestaShop was creating.

Simple fix.

In the file "prestashop/classes/Cookie.php" go down to line 50 where you see:

$this->_expire = isset($expire) ? intval($expire) : (time() + 1728000);

and change it too:

$this->_expire = isset($expire) ? intval($expire) : (time() + 3600);

This is because (some versions of) Internet Explorer seem to reject cookies that have large expiry times.

FYI: You can view the modified Presta Shop example here: http://shoestar.com.au/shop/ if you would like to test it in Internet Explorer.
