Mustafa, I updated our main server which had a lot of hiawatha tweaks. I was able to get everything running without any wigwam errors.
custom.hiawatha_standard.conf does not work, neither does custom.hiawatha.conf - I had deleted /etc/hiawatha.conf, then run cleanup, no /etc/hiawatha/hiawatha.conf created. Even switch to lightppd, then hiawatha, still no /etc/hiawatha/hiawatha.conf created.
I did it manually.
I saw in 'cleanup' cp can not stat hiawatha.conf, but it did not point to the new _standard.conf - this is a bug.
