When going to Default Config > Web I get the following error.

There has been an error processing your request

Invalid config field backend model: adminhtml/system_config_backend_web_secure_offloaderheader

On the other hand when selecting current configuration scope (Main Website) I don't get the error.

  • seems like {magento-root}/app/code/core/Mage/Adminhtml/Model/System/Config/Backend/Web/Secure/Offloaderheader.php file is missing – MeenakshiSundaram R Nov 17 '15 at 7:59
  • Thank you, but the above file does not exist in the Magento Version 1.9.0.1. Maybe another files is missing but I can not find which one. – Kostas Panoulas Nov 17 '15 at 9:30
  • MeenakshiSundaram R, You were right. That file was missing. Thank you so much! – Kostas Panoulas Nov 18 '15 at 9:37

As per the comment

{magento-root}/app/code/core/Mage/Adminhtml/Model/System/Config/Backend/Web/Sec‌​ure/Offloaderheader.php

Above file is missing in your magento, so please copy the file from fresh magento and paste it in your system.
