TikiAdmin

Use the change password page tiki-change_password.php.
Fill Username with the name of the user you want to change password, Old password with "admin-" + the admin password (not of a user with admin privs, must be the user called admin) and New password with what you want the password to be.

You must manually access the page to login, tiki-login_scr.php.
Now you'll want to put the modules you left in a disactivated column in the other one from tiki-admin_modules.php.
If you disabled both columns then you'll have to activate one from tiki-admin.php?page=features.

1) with phpMyAdmin or equivalent
- in the table users_users check that the admin user has a correct email
- in tiki_preferences set forgotPass to 'y'
- from the tikisite, goto 'I forgot my password' from the login box or go the the url tiki-remind_password.php
and send the password to admin
2) with phpMyAdmin or equivalent, you can also change the password directly in the database
- in in the table users_users set the hash to md5('adminadmin')
or update users_users set hash=md5('adminadmin') where login='admin';
Better to change the admin password interactively after to be sure all the information in the database are correctly set
3) write a little php program. Ex test.php you place in the tiki root directory

<?php
include_once('tiki-setup.php');
 $userlib->change_user_password('the_login', 'the_new_password');

and execute it http://my_domain.com/test.php

In tikiwiki1.10, add the following to each local.php:
$db_table_prefix - base table prefix
$common_users_table_prefix - common "users" prefix

In the database do
insert into users_users (login, email, hash) values('admin', 'me@me.com', md5('adminpassword'))
