I installed sagecell server on Sage5.2 and I have two problems: with jmol graphic and error messages

Edit: (Jmol resolved - the problem was in the browser, not in the server), the problem that I do not see some error reports persists. Any idea?


If the computation finishes fine, I can see the output (including plots). If the computation fails, I see empty cell (and no div with error message in Firebug). The code

throws error message on my server, as expected. However, the code

throws error on, but not on my server.

Current state

I installed the sage cell server as follows:

  1. compiled sage 5.2 from sources, tested and installed tickets 12719 and 13121 following the instructions in the description to these tickets

  2. changed host IP address in (the installation in the text only virtual machine in vmware).

  3. allowed 'ProxyPreserveHost On' in apache configuration to keep correct url's, as described in one of the posts in sage-devel

Can you help me? Many thanks.

The machine is installed on a server and apache2.conf is used to forward ports. However, the results are the same if I run the machine in VMware player and access directly from the same machine which runs the VMware player.

Jason Grout gravatar image is running version 2 of the server, which has updated the error handling. is running version 1 of the server. Indeed, it looks like aleph1 is not returning the error message either.

There isn't any development work happening on version 1 anymore (since about the beginning of summer), so this is unlikely to be fixed unless someone submits a pull request.

Thank you, I'll try version 2.
