When I attempt to view the user profile page, I get the error above.
Here's my show.html.erb code:
<% provide(:title, @user.name) %>
<div class="row">
<aside class="span4">
<section>
<h1>
<%= gravatar_for @user %>
<%= @user.name %>
</h1>
</section>
</aside>
<div class="span8">
<% if @user.microposts.any? %>
<h3>Microposts (<%= @user.microposts.count %>)</h3>
<ol class="microposts">
<%= render @microposts %>
</ol>
<%= will_paginate @microposts %>
<% end %>
</div>
</div>
where <%= render @microposts %>
is causing the problem.
Do you declare the variable @microposts
anywhere? At a glance, looks like what you should be doing is
<%= render @user.microposts %>
