[AstroPy] AstroPy Digest, Vol 147, Issue 2

Please download the latest official release of DS9 version 8.0 at:

http://ds9.si.edu/site/Download.html

It contains a fix for this issue.

In more detail, your server is returning an inappropriate MIME type for a FITS file. That being said, this is a common problem, and not the fault of the user, so DS9 now treats the MIME type “text/plain” as acceptable for a FITS file.
