Thread:Project:Support desk/MediaWiki installation doesn't work

Hi, I installed MediaWiki to by subdomain (for example wiki.website.com) but I have some problems:

- When I open the subdomain wiki.website.com I got the following message:

MediaWiki 1.17.0 LocalSettings.php not found. Please set up the wiki first.

The logo picture at the top of the page cannot be found.

- I I click the link 'Please set up the wiki first' I go to the page 'http://mw-config/index.php' instead of 'http://wiki.website.com/mw-config/index.php'. - If I open the website 'http://wiki.website.com/mw-config/index.php' directly I got the following errors: MessagesEn.php is missing.

Backtrace: --11 error codes here--

How is that possible?

The source code for my localhost and live website is also different: (but I'm using the same MediaWiki version and code)
 * Localhost: Please  set up the wiki first.
 * Live website: Please  set up the wiki first.

Thanks for the help!
