Approving often fails and displays wrong page
We’ve found recently that more often than not when we approve a message from its details view, after we click Submit, it goes to another page that’s not part of mailman. It goes to the root of our cpanel, ie same url minus the /mailman/... part, but displays the correct url in the address bar. We can reliably approve messages from the summary page.
Is this a mailman fault? Cpanel fault? DNS?
Whatever it is, it doesn’t do it for every message. Sometimes the message will be approved properly, and it’ll return to the summary view. When it does go wrong, even repeating it 10 times still fails, so it appears to be somehow triggered by particular messages. And that also discounts a DNS fault?
We have long had an issue where it displays a 404 error when we try to approve, but that was rare. This problem happens for most messages.
Ideas for diagnosis?

Sounds sort of like a rogue load balancer, caching system, or some kind of URL rewrite filter in the way.

I agree with Carl. I have no idea what the actual issue is, but given that the result has something like http://example.com/mailman/admindb/list_example.com in the address bar but the content displayed is as if the browser had done a 'GET /' would seem to say either the browser is broken - very unlikely and easily confirmed by trying a different browser - or something between the browser and the ultimate web server is the cause.

It’s happening to multiple moderators on multiple devices with independent internet connections, so it sounds like we need to ask our server provider to look into it.
Thanks, Peter Shute
