I logged in to the SS FTP site tonight to retrieve the 8.1.3 update for Solaris. Per the tech bulletin, I used the same login as I had previously used to get the 8.0 / 8.1 releases.
I was able to browse to the 8.1.3 directory, but once in the directory, I was unable to transfer the file - got a 'permission denied' error.
A problem was reported with the initial 8.1.3 release so until we could verify if there was an issue the FTP downloads were disabled. We have verified that there could be an issue viewing some orders in 8.1.3 and a fix has been made. Once QA has completed their testing the FTP downloads will be updated with a new version 8.1.3.1. Probably later today or tommorrow the FTP site will again be working for 8.1.3.1.
