I'm trying to decide between using the shopping cart or not. I only have one product for sale, but want people to be able to change the quantity. Anyway, ran into a strange issue today where I removed the cart plugin, and then the entire amember site (public and admin) gave an error because it couldn't find a file /application/library/Am/ShoppingCart.php As far as I know, there is no such file. Is that right? The first instance of this error was from /application/library/Am/App.php, line 1428 The really strange thing is I'm sure I added and removed the cart previously, with no issue, but it was a pretty big issue this time. To solve it, I added a blank php file with that filename (ShoppingCart.php) and all seems back to normal, but wanted to confirm I'm not just missing the file, and wanted to bring to Alex's attention for the bug tracker.
Yes, there is such a problem because of shopping cart specific. You need to clean-up cookies or restart browser and this problem will never appear again.
