I did a fresh install of zencart 1.39h and installed the ceon url addon. I renamed my admin and installed all of the files per the instructions. The ceon_url_mapping.php file that was in the files folder....admin/includes/functions/extrafunctions/ceon_url_mapping..... Once I install this file my admin is no longer accessible. I get a 404 error. When this file is deleted, my admin is back. Any help is appreciated. Has anyone had this problem?
