Problem with comments on page – Atahualpa

Hello there, I’m having a weird problem in my blog. Maybe you can help me.

First of all I’m using the Atahualpa theme and wordpress 2.91.

Now I will try to describe my problem. Well, the comments on pages are activated ( see the configurations – https://img683.imageshack.us/img683/3785/problem1v.jpg and https://img695.imageshack.us/img695/7172/problem2.jpg ) and working (see a page without a comment – https://www.blogdozanquetta.com/?page_id=9109 )

The problem is, when someone write a comment, the commet box disappear.

See those examples.

https://www.blogdozanquetta.com/?page_id=16386
https://www.blogdozanquetta.com/?page_id=15362

I really don’t know why. That’s not logical to me.

I don’t know if it would help, but I can paste the bfa_hor_pages.php and comments.php if someone need.

Thanks

Kai
