Recently, when using Excel 2010 or 2013 (I have both on the same Win7 machine) to publish a workbook as a webpage to my Comcast FTP host site, the supporting files (graphics, etc.) are no longer being FTP'd to the host site. Just 2 files are ftp'd, the main HTM file and maybe a .css cascading stylesheet file. There should be a file for each tab in the workbook and lots of graphics files. I've been doing this for years and it just started doing this.
Excel will still output the necessary html and suppotring files to the local drive, but will not directly FTP them to the host. I have to use a 3rd party FTP product to upload them now.
I have played with all the settings, tried a different machine, and even tried publishing to a different host site, and the problem continues. I suspect an update to Windows or Office is the issue. Any ideas?
