This works fine for me:

$ cat cgiapp.pl 
#!/usr/local/bin/perl
use warnings;
use strict;

TestApp->new->run;

package TestApp;
use base qw|CGI::Application|;
use CGI::Application::Plugin::AutoRunmode;
use CGI::Application::Plugin::Session;

sub default : StartRunmode {
  my $self = shift; my $output;

  # get current access count
  my $access_count = $self->session->param('access_count') || 0;

  # increment access count
  $access_count++;

  # store new access count in session
  $self->session->param(access_count => $access_count);

  # get CGI object out of application
  my $q = $self->query;

  #build output
  $output  = $q->start_html(
    -head => $q->meta({
      -http_equiv => 'Content-Type',
      -content    => 'text/html; charset=UTF-8'
    }),
    -title => 'access count application'
  );
  $output .= $q->div("accessed $access_count time(s) this session");
  $output .= $q->div(' ');
  $output .= $q->div( $q->a( {-href => $q->self_url} => 'access again'
+ ) );
  $output .= $q->end_html;

  # set charset
  $self->header_add( -type => "text/html; charset=UTF-8");

  # give output to app to send to user
  return( $output );
}

$ perl cgiapp.pl

I'm sure if you run the code on the server, perhaps in the debugger, the cause of the problem will quickly jump out at you.
