Hi jdrago_999,

Thanks for the reply.

Yes, I did try the sample code and that all works fine. I am happy that my mod_perl/perl/Apache are all installed ok.

My site works fine using HTML::Template. When I switch to use Template I get the error:

[Wed Apr 01 09:28:54 2009] [crit] (22)Invalid argument: Parent: Failed
+ to create the child process.
[Wed Apr 01 09:28:54 2009] [crit] (OS 6)The handle is invalid.  : mast
+er_main: create child process failed. Exiting.
[Wed Apr 01 09:28:54 2009] [notice] Parent: Forcing termination of chi
+ld process 2670888

Everything works fine from the command-line, it just crashes when I run through apache.
I have set up my site so that the template engine is swappable and am using HTML::Template::Filter::TT2; so that the templates are exactly the same between HTML::Template and Template::Toolkit
Here is the working Template code for HTML::Template

sub Render
{
    my $proto = shift;
    my ($params, $data, $template, $base_template_dir) = @_;

    my $engine = HTML::Template::Expr->new(filter => \&ht_tt2_filter,
                                             filename => $base_templat
+e_dir.'/'.$template, 
                                             die_on_bad_params=>0,
                                             encoding => ':utf8');

    $engine->param($params);
    $engine->param($data);
    
    print $engine->output;

}

Here is the corresponding code for Template::Toolkit which crashes

sub Render
{
    my $proto = shift;
    my ($params, $data, $template, $base_template_dir) = @_;

    my $tt = Template->new({INCLUDE_PATH => $base_template_dir,
                            INTERPOLATE  => 1}) 
                           || croak("$Template::ERROR\n");


    $tt->process($template, { params => $params, data => $data } );

}

and are called are called via

$TEMPLATE_ENGINE->Render(@_, $TEMPLATE_DIR);

where $TEMPLATE_ENGINE is the appropriate prototype.

I'd appreciate any help you can give me.

Thanks
