[pmwiki-users] Need help with Clean URLS

[Philip Stitt]

Ok, I put everything in a folder named "pmwiki", and changed "index.php"
back to "pmwiki.php". I'm still getting the same results, basically:
"http://example.com" gives me a 404, but "http://example.com/pmwiki"
works fine. Links off of that page point to clean URLs, like:
"http://example.com/SomeGroup/SomePage"
but I still get a 404 on those pages. The dynamic URLs, like:
"http://example.com/pmwiki/pmwiki.php?n=SomeGroup.SomePage" still work.
What I'd like is
"http://example.com/SomeGroup/SomePage"
 
This is the part I don't understand: On the page
http://www.pmwiki.org/wiki/Cookbook/CleanUrls , in "Example One" it
shows:

$ScriptUrl = "http://server.example.com/~someuser/pmwiki";
  
What does "server" mean, what am I supposed to put there? And what is
"~someuser" supposed to be? I'm sorry I don't get that. Is "~someuser"
just a supposed webfolder? I'm using:

$ScriptUrl = "http://example.com/pmwiki";

Is this wrong? 

Thanks,
Phil
