Thread:Project:Support desk/.htaccess and sidebar

Hi, my name is Yannick and I'm from Italy. English is not my best :(

I have installed mediawiki 1.20.5 on a website already started. All ok except 2 things:

1) There isn't the .htaccess in any root and I don't know how to create one for this platform; 2) I am going to modify the sidebar but... how? I changed (in localsetting.php) the default skin to "monobook" and if I am going to */wiki/MediaWiki:Sidebar I have a 404 page

Can you help me?

Thank you very much Yannick

Ps: without an administration panel this platform is not exactly easy :)
