I have just reinstalled my Mailman (on Debian with apt-get). It recognized the old settings and it can display the old lists, members, etc.

But if I want to manage old lists with admin front-end by Apache-webserver, it send erros messages:

When I am prompted to write admin password, the top screen:

"Error decoding authorization cookie."

When I type it and hit Enter, the message is:

admin: Traceback (innermost last): admin: File "/var/lib/mailman/scripts/driver", line 112, in run_main admin: main() admin: File "/usr/lib/mailman/Mailman/Cgi/admin.py", line 168, in main admin: FormatConfiguration(doc, lst, category, category_suffix) admin: File "/usr/lib/mailman/Mailman/Cgi/admin.py", line 306, in FormatConfig admin: form.AddItem(FormatOptionsSection(category, lst)) admin: File "/usr/lib/mailman/Mailman/Cgi/admin.py", line 361, in FormatOption admin: AddOptionsTableItem(big_table, item, category, lst) admin: File "/usr/lib/mailman/Mailman/Cgi/admin.py", line 376, in AddOptionsTa admin: val = GetItemGuiValue(lst, kind, varname, params) admin: File "/usr/lib/mailman/Mailman/Cgi/admin.py", line 463, in GetItemGuiVa admin: return TextBox(varname, getattr(lst, varname), params) admin: AttributeError: num_spawns

Could anybody help this problem solving. I do not want to loose my old lists (more then 1000 members)

Thanks
