ts just Operating System changed from Windows 2008 R2 to Windows 2012 R2 with IIS 8, rest all is same including Plesk, ASP.NET, MSSQL, your SSL etc. nothing else is changed Sam: the developer of this cart can fix it immediately for you
I guessing that they didn't turn on classic .asp Windows 2012 R2 with IIS 8 has that turned off by default I believe. In any case, you are in good hands with Phil and it looks like he's on the job.
