When we put a "subscribe to RSS" link on sub-blogs of our Nucleus CMS system, which means all other blogs are in the same directory as the 1st Nucleus Blog, they're all re-direct to the first blog, Ftruscot show us the way to overcome this problem.

We have 5 blogs resides in 1 directory http://ltooz.com/ltooz341/

May be we should have made seperate directory for each blog like

http://ltooz.com/audis, http://ltooz.com/nucleuscms, etc.

Normal code for original code should be

<div id="rss"><a href="<%blogsetting(url)%>xml-rss2.php">Subscribe to RSS</a></div>

We have to change it to

<%if(skintype,error)%>
<%elseif(skintype,member)%>
<%else%>
   <div id="rss"><a href="<%sitevar(url)%>xml-rss2.php?blogid=<%blogsetting(id)%>">Subscribe to RSS</a></div>
<%endif%>

Now every blog works.

Thanks Frank!!!!
