Thank you for trying to help.
I have already posted on the wordpress forum, I will contact my host provider, hopefully they can do something.

I will keep you posted

Hi there,

It sounds like you're having general WordPress issues. Unfortunately the theme doesn't have control over the issues you're experiencing.

The best advice we can provide is to either visit the WordPress support page at http://wordpress.org/support OR contact your host provider and have them revert your site settings to a backup.

Sorry, but these issues go beyond general theme support.

Hope you understand.

Chris

The problem is that I can't even seem to access my log in screen without it redirecting me toward this messed-up page.
:(

Without access theres not much support we can provide. You should be able to use the Wordpress Forgot My Password link at the login screen. I would do that first, then undo whatever you changed.

The were two boxes with the possibility to insert the link toward my website.

both were http://www.sreykasmile.org
I changed the 2nd of the two to http://www.sreykasmile.org/en

if I recall correctly, the bigest issue is that i seem to have lost access to the dashboard... well that and the theme, and the login option...

Can you provide some more information on exactly what you edited in the General Settings?

Please Help me !!!
I have made a big mistake when editing the link in the WP "general settings"
now my website is all messed up http://www.sreykasmile.org/en/wp-login.php?action=logout&_wpnonce=cc2e800b39
The style sheet is gone, and I have lost acces to my login. I don't know how to acces the backoffice again.
