You nailed it. Nice one. MultiViews is set as one of the default options 
in the UserDir <Directory> options. It sets:

    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec

A replacement with

    Options Indexes FollowSymLinks

not only fixed the problem, but speeded things up a bit.

For completion, I tried this. When I tried to create Readme.Homepage 
PmWiki responded with:

    PmWiki can't process your request
    ?invalid page name
    We are sorry for any inconvenience.

So I rejigged, created it, and unrejigged, and when I tried to access it 
I received the same message.

And a most excellent one. Thanks very much, Patrick. You're not as green 
as you're cabbage looking, as they say hereabouts :-)
