I have a situation where my client's admin url is something like this;
http://www.example.com/index.php/admin/admin/dashboard/index/key/0981a6bd2f5a06fec85d3c9e297849a0/
the word admin occurs twice, how to remove one. i checked app/etc/local.xml and in magento admin->system->configuration->admin, there was no changes in the default setting.
