Now this is potentially very interesting! First invocation of app after
server restart loads template OK, and Data::Dumper(Configs->AT_CONFIG)
says:

$VAR1 = {
          'default_type' => 'TemplateToolkit',
          'TemplateToolkit' => {
                                 'INTERPOLATE' => '1',
                                 'WRAPPER' => 'hilis.tmpl',
                                 'TAG_STYLE' => 'asp'
                               },
          'include_paths' => [
                               '/127.0.0.1/perl/hilis4/templates',
                               '/127.0.0.1/perl/hilis4/templates/HILIS4'
                             ]
        };

But second and subsequent invocations (ie hit browser reload button) get
error message, and Data::Dumper says:

$VAR1 = {
          'TemplateToolkit' => {
                                 'INTERPOLATE' => '1',
                                 'WRAPPER' => 'hilis.tmpl',
                                 'TAG_STYLE' => 'asp'
                               }
        };

ie part of the AT_CONFIG is missing (default_type and include_paths).
That could explain why it is defaulting to HTML::Template and cannot
then find a template file. But what is causing this behaviour?

I will try your setup tomorrow when I have a little time, but I don't
recognise your PerlHandler code so maybe I have not set Apache/mod_perl
up correctly? There is no mention of my module in httpd.conf or
perl.conf, I just invoke the application via the browser, and Apache
knows to run applications from the /127.0.0.1/perl/ directory using
'PerlResponseHandler ModPerl::Registry' (mod_perl 1.99). Perhaps this is
the problem?
