yet another Whoops! Your session has expired.

Hi,

Yet another thread about it, I've read quite few of them, but can't solve it.

The site is set to have products display in homepage, and when adding to cart I get the whoops message, a few times when logging in the item is in the cart, and a couple times it is not, to add to the wierd behaviour, without closing the browser I then tried to go to product page, and order from there, and the cart is displayed with the item in it.

It does the same with classic template.

Tried both in firefox and chrome, same behaviour.

Extra info:
Recently I installed SSL

Thank you

Did some more testing:

It happens the first time I open a new browser window/tab, on the homepage/product listing if I go back to the homepage/product listing it let's me add and displays the cart.

It seems the problem occurs when I have not yet navigated the site from homepage/product listing, as when I go to any other page, and come back to homepage/product listing it works fine; and it does so also when starting the new tab with a specific product page.

It seems to be fine now.

It turns out to be the configuration files, where I had https://www.example.com for the SSL, I put example.com, and seems to be fixed, did few tests already and no error.
