That's interesting. I'm testing a new site (http://babyongrand.com) and am getting "Unknown" in the From field for admin order notifcations.

I've checked and made sure that the Store Name is filled in at /admin/store/settings/store/, and an e-mail address is entered both on /admin/settings/site-information and /admin/store/settings/store.

The Store Name is "Baby Grand" and the e-mail is info@.... I'm not completely sure which should be showing up in the From field, but in any case it isn't working.

Thanks for your help,

Jim
