incredibly, but looks like chrome doesn’t support feeds without an extension…
here there’s a way of getting support for rss in chrome
i adapted the technique for use in my rss button
so if browser is chrome = true, change value of href:
<?php
$isChrome = eregi("chrome", $_SERVER['HTTP_USER_AGENT']);
$rss = $MY_NORMAL_RSS_URL;
if($isChrome) $rss="javascript:(%7BaddURL:function(aURL)%7Bvar%20url=%22https://feeds.ramisp.org/preview.php?utf=y&src=%22+encodeURIComponent(aURL);location.href=url;%7D,getFeedURL:function(e,aDocument)%7Bvar%20j=e;var%20c=aDocument.location;if(e.indexOf(%22/%22)!=0)%7Bvar%20d=c.pathname.split(%22/%22);d%5Bd.length-1%5D=e;j=d.join(%22/%22)%7Dreturn%20c.protocol+%22//%22+c.hostname+j;%7D,checkForFeeds:function()%7Bvar%20f=false;var%20m=document.getElementsByTagName(%22link%22);for(var%20g=0,a;a=m%5Bg%5D;g++)%7Bvar%20h=a.getAttribute(%22type%22);var%20i=a.getAttribute(%22rel%22);if(h&&h.match(/%5B%5C+%5C/%5Dxml%24/)&&i&&i==%22alternate%22)%7Bvar%20b=a.getAttribute(%22href%22);if(b.indexOf(%22http%22)!=0)%7Bb=this.getFeedURL(b,document);%7Dthis.addURL(b);f=true;break%7D%7Dif(!f)alert(%22Oops.%20Can't%20find%20a%20feed.%22);%7D%7D).checkForFeeds();";
?>
<a href="<?php echo $rss; ?>" target="_blank"><img src="/images/rss.png" alt="RSS Feed" title="RSS Feed" /></a>
