Display Log Files [Support Thread] (v1.5.1-to-v1.5.6)

[Limitless]

The error message indicates that the constant DIR_FS_LOGS is not defined so that the PHP dir function is choking. Running on v1.5.1, you should have the DIR_FS_LOGS constant defined in both /YOUR_ADMIN/includes/configure.php and /includes/configure.php. I'm guessing that this was an upgrade to v1.5.1 for your site.

That said, the plugin shouldn't be giving you the white-screen-of-death. I don't seem to have an issue with or without the DIR_FS_LOGS constant on v1.5.1 because the Zen Cart init handlers 'fix' it. It's another story on v1.5.0, however, where I'm seeing what you're seeing.

Make the changes highlighted in red to /YOUR_ADMIN/display_logs.php, starting at line 39:

     foreach(array(DIR_FS_LOGS, DIR_FS_SQL_CACHE, DIR_FS_CATALOG . '/includes/modules/payment/paypal/logs') as $logFolder) {
      $logFolder = rtrim($logFolder, '/'); 
      $dir = @dir($logFolder);
      if ($dir != NULL) {
        while ($file = $dir->read()) {
          if ( ($file != '.') && ($file != '..') && substr($file, 0, 1) != '.') {
            if (preg_match('/^(myDEBUG-|AIM_Debug_|SIM_Debug_|FirstData_Debug_|Linkpoint_Debug_|Paypal|paypal|ipn_|zcInstall).*\.log$/', $file)) {
              $hash = sha1 ($logFolder . '/' . $file);
              $logFiles[$hash] = array ( 'name'  => $logFolder . '/' . $file,
                                         'mtime' => filemtime($logFolder . '/' . $file)
                                       );
            }
          }
        }
      }

I'll hold off on resubmission to the Plugins for a bit, just in case ...

These changes fixed the 500 error on 1.50.

Thanks for this addition!
