RSS dont works

the rss in my site don´t works... I've enabled in config, but the url of my shop dont works

www.nuestrasbandasdemusica.com/tienda.html

www.nuestrasbandasdemusica.com/tienda/type-rss.feed

Can you help me?

It sounds like a problem of SEF. Could you deactivate the SEF temporarily on your website and try again ? Does it work with the SEF deactivated ?
Which SEF extension do you use and which version ?

Does it work with the SEF deactivated ?
YES, With Sef deactivated works, but i need that my page have SEF activated...

Which SEF extension do you use and which version?
I'm use the default Joomla 1.7 SEF in global configuration. I do not use any component for SEF...

Ok. Then it's really a problem with the SEF on joomla 1.7.
What is the URL of the RSS feed when the SEF is deactivated ?

the ur is:
www.nuestrasbandasdemusica.com/index.php...format=feed&type=rss

Could you try to replace the code:

$link = '&format=feed&limitstart=';

by:
global $Itemid;
$menus = &JSite::getMenu();
$menu = $menus->getActive();
if(empty($menu)){
if(!empty($Itemid)){
$menus->setActive($Itemid);
$menu = $menus->getItem($Itemid);
}
}
$url_itemid = '';
if(!empty($Itemid)){
$url_itemid = '&Itemid='.(int)$Itemid;
}
$link = 'index.php?option=com_hikashop&ctrl=product&task=listing&cid='.$pageInfo->filter->cid.$url_itemid.'&format=feed&limitstart=';

in the file components/com_hikashop/views/product/view.html.php and try again ?

in this file the are two lines with this code:

line 224 and line 229, wich i replace?

Thanks

Both please.

i change these lines, but don't work

you can see the test page where i make these changes barbernardo.com/tienda.html

It's strange that your SEFed URL is:
www.nuestrasbandasdemusica.com/tienda/type-rss.feed
It should be:
www.nuestrasbandasdemusica.com/tienda/type-rss?format=feed
I just tried on our end and that's what we have on our joomla 1.7 test website.
That URL is converted by joomla using the non SEFed URL that HikaShop gives.
Looking online for that problem, I found that thread:
community.getk2.org/forum/topics/rss-feeds-not-working-when-add
It's exactly that problem so I suppose that what they propose should fix your issue too.
