But this is for the post, not for the page, or i’m wrong?

Please try reading the pages at the links I gave above.

Ok, thanks, but I don’t understand one thing. I have to insert this code to one of the existing files on the theme that i’m currently using, or how and were I insert this code.

Probably within your theme’s index.php template file. It really depends upon how your theme is put together.

ok i’ll try to fix it. Tomorrow I’ll say something. Thanks very much!!

Thank you very much! After some tests now all works.

Also if it’s not about this topic, i want to ask you another question. Do you now a good subscription plugin, to do that users receive a mail every new post that i publish?

thank you very much for all!

Try setting up a Feedburner account and then using a Feedburner plugin.

I have some problems with this program. I put all the things, but I don’t know how to subscribe people. I add a plugin but it says that my Feedburner does not allow email subscriptions.

But I don’t know how to enable it.
