I've stopped trying to get the entire login file to work and am now just trying to work on it step by step. I made a test.cgi that just tries to open the directory, print out the files in the directory, open a file in the directory, and print all the lines in the file. So far this test file has been failing. I have other cgi files in the same directory that work just fine. The other files, such as a register.cgi, are a lot more complicated than the login.cgi and test.cgi. This is confusing to me because the register.cgi and some others open directories and files just fine (some open the same directory and files that login and test have failed to open). My ISP is running their Apache server on a Linux based OS. I don't think I can gain access to changing anything on the httpd.config file. The I've checked the permissions on the test.cgi and it's 0755. Also, the error log that is really not making sense to me says this:

The test.cgi is simpler than the login one that I was initially trying to get to work. The code for it is as follows:

#!/usr/bin/perl -wT

use CGI qw(:standard);
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);
use strict;

my (
    $dir,            #path to directory
    $dir_file,        #sample file in the directory
    @files,            #array of all the files in the directory
    @lines            #array of all the lines in the sample file
);

$dir = "/home/hopefulc/public_html/cgi-bin/";
$dir_file = "/home/hopefulc/public_html/cgi-bin/koh_members_list.cgi";

opendir(DIR, $dir) || die("Failed To Open Directory");
@files = readdir(DIR);
close(DIR);

print header;
print start_html("Test CGI");

print "<u><h3>The files in the directory are listed below:</h3></u>\n<
+br><br>\n";

foreach my $file (@files)
{
    print "$file\n<br>\n";
}

print "<u><h3>The lines in the file are listed below:</h3></u>\n<br><b
+r>\n";

open (FILE, $dir_file) || die("Failed To Open File");
@lines = <FILE>;
close(FILE);

foreach my $line (@lines)
{
    print "$line\n<br>\n";
}

print end_html;

If anyone knows what could or might be causing this, it would be greatly appreciated...
