RewriteRule ^wiki/?(.*)$ /w/index.php?title=$1 [L,QSA]
So I suggest you try changing that line to the correct
conditions for your
site.
So to change
http://www.mysite.com/index.php?title=Article to
http://www.mysite.com/index.php/title=Article or better
http://www.mysite.com/Article what I have to write in .htaccess?
Excuse me but I don't know how to use rewrite.
Many thanks,
Giovanni
