error/admin/installhijacked

This error compares $adminuser->lastip with the users current IP address.

It will occur if a site has been installed on a server via the cli scripts in admin/cli (install_database.php or install.php). After installing the site remotely, visiting the site via a web browser (a different IP) will trigger the error message.

Workaround:

Update the database directly with your current IP address (table: mdl_user, field: lastip, SQL: UPDATE mdl_user set lastip='<ip address here>' where username='admin';).
