Trying to enable Mana in ktd gives "Cannot detect mana server at https://mana-test.koha-community.org, please ask an administrator to check your configuration." Comparing what https://mana-kb.koha-community.org/ and https://mana-test.koha-community.org/ serve to a browser, it sure looks like the Mana server isn't running on mana-test.
I find the same to be true with https://mana.koha-community.org. ping: cannot resolve https://mana.koha-community.org: Unknown host
In my default KTD config: <mana_config>https://mana-test.koha-community.org</mana_config>
Perhaps the same person the wiki says manages mana-kb also manages mana-test?
