Hello, This is a weird error I get. Hope that it can be useful to track down a bug. I've got a base (Data.bbb.*) that is served by a PCGI/Apache Zope. When I publish this base with ZopeHTTPServer, no problemo, it just work fine. However, If I try to publish the base with ZServer, I get this traceback: -------------------------------8<------------------------------- Traceback (innermost last): File "./PubCore/ZServerPublisher.py", line 94, in __init__ publish_module( File "/home/webdevel/devel/Zope/lib/python/ZPublisher/Publish.py", line 877, in publish_module response = publisher.publish(module_name,after_list, File "/home/webdevel/devel/Zope/lib/python/ZPublisher/Publish.py", line 325, in publish (bobo_before, bobo_after, request_params, File "/home/webdevel/devel/Zope/lib/python/ZPublisher/Publish.py", line 616, in get_module_info module=__import__(module_name, globals(), globals(), ('__doc__',)) File "/home/webdevel/devel/Zope/lib/python/Main.py", line 103, in ?

I copied them with cp -R to do my tests: $ cp -R ZopeWithPCGI ZopeWithZHS $ cp -R ZopeWithPCGI ZopeWithZS $ cd ZopeWithZHS; ./start.py # it works. Then I shutdown the Zope process $ cd ZopeWithZS/var; ../ZServer/start.py # don't work. I wanted to "suck" all my sources from my site by FTP with ZServer to work on it offline, but I can't because of this stuff :-))) Hope that can help. And if anyone here has a solution, it is also welcome... Regards, Jephte CLAIN, Service Informatique CHSR
