   <apex:styleSheet value="{!URLFOR($Resource.saasblog,'images/default.css')}"/>
<div id="body">
<!-- start header -->
<div id="header">
    <div id="logo">
        <h1><a href="#">SaaS Blog</a></h1>
        <h2>Build on Force.com</h2>
    </div>
    <div id="menu">
        <ul>  
        <apex:form >
            <li class="active"><a href="#">home</a></li>
            <li><a href="/apex/SiteLogin">login</a></li>
        
            <li><apex:commandLink action="{!handleNewPostClick}"> new post</apex:commandlink></li>
    
            <li><a href="#">about</a></li>
            <li><a href="#">contact</a></li>
          </apex:form>
        </ul>
    </div>
</div>
<!-- end header -->
<!-- start page -->
<div id="page">
    <!-- start content -->
    <div id="content">
        <!-- start latest-post -->
        <div id="latest-post" class="post">
        <h1 class="title">{!Blog_Post__c.Name}</h1>
        <p class="meta"><small>Posted by {!Blog_Post__c.CreatedBy.name} on {!Blog_Post__c.CreatedDate}<br />
                Filed under <a href="#">[labels]</a></small></p>
        <div class="entry">
                {!Blog_Post__c.Post__c}               
        </div>
      </div>
      <div id="recent-posts">
          <apex:repeat value="{!Posts}" var="post">
            <div class="post">
                <a class="title" href="/apex/template?id={!post.Id}" >{!post.Name}</a>
                <p class="meta"><small>Posted by {!post.CreatedBy.Name} on {!post.CreatedDate}<br />
                  Filed under <a href="#">Uncategorized</a> </p>
                </div>
           </apex:repeat>
            </div>
        </div> 
    </div>  
<!-- end page -->  
 </div>
 </apex:page>

This is the VF page

Page permissions, apex classes or object permissions are the most obvious thing to check first. Check the profile for the portal user and make sure that they ahve access to the class, pages, and objects that you want them to access.

You may need to login as admin of your developer account and configure the portal user profile from there. The profiles are accessible from Setup > Manage Users > Profiles. Check out the Apex, Object, and VisualForce page permissions for the portal user profile there.

Cheers,
