Strange one, this started happening somewhat randomly or at least, I don't recall changing anything from what it did work. Interestingly all the information comes across to the sidecart correctly other than the image. I've echo'ed out what I'm passing as the image and the URL is fine, however, in the cart it reports the URL incorrectly. But when clicking go to checkout, it reports the cart empty. Like it isn't setting the session. I've tried this on multiple browsers and multiple computers.
Does anyone have an idea what is happening here? I'm using validation on the product form, however, it usually kicks out an error if there is something wrong there. The Cart count is correct across pages. It just forgets everything when you go to checkout. Also the image is not loading.
