Q: Owner company or administrators are missing!!! How can I fix this?

A: If activeCollab sais that owner company or administrator are missing you will need to manually create them. Use "phpMyAdmin":http://www.phpmyadmin.net/home_page/index.php or any other MySQL management tool to work with the database directly.

Start by inserting company row in companies table (may have prefix, usually ac_). Make sure that fields have following values:

id => 1
name => Your company name (use your organization name)
client_of_id => 0
created_by_id => 1
created_on => pick current date

Now create a new user in users table:

id => 1
company_id => 1
username => Your username
email => Your email address
token => 0a92df346e3a833cae214d65af35e69b3cf4e5ab
salt => 6d093346fa02f
twister => 4982716305
is_admin => 1
auto_assign => 1
created_on => pick current date
updated_on => pick current date

That should do the trick. Your password will be '123' (without quotes).
