Can i have access to my WordPress Website again?

You need to look in your database in the wp_options table. There are two rows in the table that are relevant: look for siteurl and home – one or both of them will need to be edited, and updated to the correct url.

Alternatively you can edit your wp-config.php file and add the following lines:

define('WP_HOME','http://www.e-cooking.pingfiles.fr');
define('WP_SITEURL','http://www.e-cooking.pingfiles.fr');

I got my information from the Codex, here.
