With the upgrade to drupal-5.14 and using the SecurePages 5.x-1.7-beta1 module:
Error:
PHP Fatal error: Call to undefined function drupal_urlencode() in /path/to/drupal/sites/all/modules/securepages/securepages.module on line 323
Solution:
Added the below code to the beginning of the securepages_init function in "securepages.module" so function gets loaded.
if (!function_exists('drupal_urlencode')) {
include_once 'includes/common.inc';
