I have a live site where there is suddenly a huge issue. Upon purchase RANDOMLY the order data gets overwritten. IE THE customer data is wrong, being overwritten with some other user's data.
Obviously this sounds like a session issue so I went to set Recreate Session = true in the admin and with it on, no one can actually login. it ACTS like it logged in, IE showing 2 in cart after login for me, but if I Click the cart it tells me to login again.
How might i debug this issue?
