Hi Zopistas, I have two old Data.fs files, circa November 1999 and April 2000. Perhaps not surprisingly, I can't seem to use them with Zope 2.1+. ZServer fires up but both the site and the ZMI of the site give the following traceback: Site Error An error was encountered while publishing this resource. AttributeError Traceback (innermost last): File C:\ZOPE\OSCWEB\lib\python\ZPublisher\Publish.py, line 223, in publish_module File C:\ZOPE\OSCWEB\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\ZOPE\OSCWEB\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File C:\ZOPE\OSCWEB\lib\python\ZPublisher\Publish.py, line 162, in publish File C:\ZOPE\OSCWEB\lib\python\ZPublisher\BaseRequest.py, line 444, in traverse File C:\ZOPE\OSCWEB\lib\python\ZPublisher\BaseRequest.py, line 520, in old_validation (Object: broken) AttributeError: __getitem__ I can imagine that some external products might be missing, but I wouldn't think this would stop the ZMI from displaying properly? The first four bytes of the file are FS21 - this wouldn't be a magic number by chance? Any advice on how to get this data into a modern ZODB? Cheers, Darran.
