I have downloaded Zope 2.5.1 both as the source distribution and as the linux distribution. I have installed the source distribution onto an SGI running IRIX 6.5 (running python2 w_pcgi.py and then start) and installed the linux distribution onto a Linux box running RedHat 6.2 (running the install script and then start). In both cases, I can connect to http://hostname:8080/, login with the initial admin account, and get the initial index page with no difficulty. However, if I select the link to the Zope Management Interface, I get the three frames, but only the top one fills with anything. I get two "Document contains no data" dialogs. When I check the server it has dumped core and the shell window indicates that the server has restarted. No error messages are apparent in either the shell window or the var/Z2.log file. Since I have exactly the same problem in two completely different installs, but can find no similar complaints in the mail archives, I suspect I am doing some so completely newbie mistake that no one even mentions it. However, I am clearly stumped and would appreciate some help. As an additional data point, I actually tried the Zope 2.5.0 install on the SGI box as well. I had a similar problem, although then I did get the lower right frame and could perform some of the tasks. However, I wasn't able to get it to add the Zope Tutorial. Again the symptoms on the server side were core dumps with no apparent error messages in the logs. Finally, just for the record, I have tested this with Netscape 4.79 on the SGI, as well as Netscape 4.72 and 6.2 under Windows NT. Same problem with each. So it does not appear to be a browser problem. (Actually if some browser problem could crash the server, that would be rather scary anyway.) Thanks, Malcolm
