Fatal error: Call to undefined function drupal_add_js() in ./modules/node_redirect/node_redirect.module on line 161

When I change cache mode to normal, everything appears to work fine until I access the node_redirect.module. After I using this module and logging out, I cannot access any of the pages on the site. I receive the following fatal error on all pages: Fatal error: Call to undefined function drupal_add_js() in ./modules/node_redirect/node_redirect.module on line 161. At this point I have to remove the node_redirect directory so that I can log back in and disable caching. When I disable caching, everything works fine but the site runs slow.
