Hello, I run three separate Mailman servers (all low volume). Yesterday evening I encountered a weird problem with 2 of them:
It seemed as if (a) cookies had stopped working or (b) a strange permissions problem occurred because although I could log in to the admindb page for all my lists with no problem, an attempt to approve a vetoed message just returned me to the login screen. Likewise, an attempt to switch between the various admin pages led me straight back to the login, even though I could happily authenticate to each individually.
The strange thing is that this happened only on 2 out of 3 machines, even though Mailman is configured identically on all. I do not think it is a webserver problem because the two machines run different software. Even more strangely, today everything is working fine!
I'd be grateful for any thoughts.
Matthew
