Hello, Running galaxy-cloud latest release on amazon EC2, configuration out of the box except for: host = 0.0.0.0 I can upload data, run tools, but when I click on the 'eye' icon to view the data , the middle panel is empty (accessing galaxy cloud from Firefox and Chrome on CentOS linux). I tried creating a simple fasta file. It shows fine on the right panel, but won't display in the middle panel. View parameters displays correctly. Only the actual data is not displayed. The log shows no error: 146.129.249.238 - - [10/Mar/2011:02:19:52 +0000] "GET /datasets/5969b1f7201f12ae/display/?preview=True HTTP/1.1" 200 - "http://ec2-xxxxxx.compute-1.amazonaws.com:8080/history?show_deleted=False" "Mozilla/5.0 (X11; Linux i686 (x86_64)) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.697.0 Safari/534.24" Our local instance of Galaxy does not have this issue, only the cloud instance. Since this is a total blocker, any hint is *very* gratefully received, Isabelle -- Isabelle Phan, DPhil Seattle Biomedical Research Institute +1(206)256 7113
