We upgraded GW 7.02 to 7.03 hp2 on a new server, install failed. Some worked, some features did not. It turned out our certificate server was our old mail server, when I removed it from the tree, it resulted in a poor install. I started over, rebuilding the server from scratch. Now, when a user tries WebAccess login, the screen shows momentarily then flashes white. It will not accept any login info. Our fix is to have users delete their browsing history in Internet Explorer. (Safari users have no problems). However, with hundreds of users, I'd like to force the issue, if possible, from the server. It would help users a lot. Or, is deleting the browsing history the simplest approach?
