Hello,

You have right sorry.
I installed the One Page Checkout plugin.

By the way I find out there is no relation with the plugin. This is a bug of joomla 2.5 I think.
Thank you

Even I do not think it is a bug of Joomla! 2.5. You need to check with your hosting service provider and get the correct email settings which you need to incorporate in Joomla Global Configuration so that Joomla! can send email from your server.

The problem is like this; the system emails are sending to registered users but not sending to super user or administrators.
Because of this I am thinking that the problem is caused of joomla bug.
Anyway thanks for your interest, I am searching the solution on joomla forums.

Ok.
