mysite is the host. So I have mounted xowiki at mysite.com/wiki. However, I am using the host-node map so myhost.com is actually mainsite.com/mysite. Just occured to me that this might be part of the problem so I tried accessing the package via mainsite and sure enough, everything seems to work fine. This is not a possible solution for me though. Any idea as to why this is happening?
Yes, I can get to wiki/admin but "set index_page en:index" is there already. There appears to be a default index page as well. Everything works OK when I bypass the host-node map.
