Re:Admin Password
Go to tiki_preferences table of your database.
Search for forgotPass, if it says 'y' leave if 'n' change to 'y'.
Go to tiki_users_users table of your database.
Search for 'admin' in the login field and ensure your email address is there
Go to tiki-remind_password.php page on your tiki site.
Enter your user name and press 'send me my password'.
Good Luck! 😀
