Login and coupon code (cache?)
Two more issues while testing (usedpianomusic.com)
(1) I created a user account on the store site to make test purchases, and every time I sign out the site "forgets" my password. I have reset it three times and it doesn't seem to store it or something. I've tried it using Chrome and Firefox.
(2) In Chrome after I signed out of my test account and after using a coupon code (which worked successfully), it seems to be retaining the code and adjusting ALL the items globally showing each item on sale at 10% off (the coupon code was 10%). I switched over to Firefox and it wasn't showing this error, but I didn't get to test it further since I was having trouble with item (1) above.
UPDATE: I just tested the login issue again on both web browsers and it appears that the issue occurs AFTER placing an order and then logging out. Before doing so, I logged in and out about five times on each browser platform and no issue. As soon as I placed an order and the logged out, I couldn't log back in with the same password.
