moving wordpress from subdomain to root

Hello !

I’ve now moved my new site from a subdomain (staging.markritchie.ch) to the root (markritchie.ch), always following the codex instructions here: http://codex.wordpress.org/Moving_WordPress

Here is what I get:
Warning: require_once(/hsphere/local/home/gdjeunes/staging.markritchie.ch/wp-load.php) [function.require-once]: failed to open stream: No such file or directory in /hsphere/local/home/gdjeunes/staging.markritchie.ch/wp-blog-header.php on line 12

Fatal error: require_once() [function.require]: Failed opening required ‘/hsphere/local/home/gdjeunes/staging.markritchie.ch/wp-load.php’ (include_path=’.:/hsphere/shared/apache/libexec/php5ext/php/’) in /hsphere/local/home/gdjeunes/staging.markritchie.ch/wp-blog-header.php on line 12

the markritchie.ch/readme.html file works, so I believe the files are ok.
I tried changing the wordpress and site urls with wp-config file. No result.

Can anyone help me ?

Thank you very much.
