changed my admin url from index.php/admin to something else don't remember it. Can anyone tell me how to get back into my dashboard.
You can change the admin url in:
As @brentwpeterson wrote in
<admin> <routers> <adminhtml> <args> <frontName><![CDATA[admin]]></frontName> </args> </adminhtml> </routers> </admin>
admin panel -> System -> Configuration -> ADVANCED -> Admin -> Admin Base URL -> Use Custom Admin URL / Use Custom Admin Path. But if you changed it there and can't login in the admin panel you should revert it in the database. The SQL queries are:
UPDATE core_config_data SET value = 0 WHERE path = 'admin/url/use_custom';
UPDATE core_config_data SET value = 0 WHERE path = 'admin/url/use_custom_path';
