Note: I'm working specifically with WordPress, but this is likely applicable to APS packages in general. I'm trying to write a script that installs WordPress for users automatically via the REST API. I've reached the point where no errors are generated, and information gets entered into the aps_instances and aps_instances_settings tables, but the installation never actually kicks off, and the instance_status in aps_instances stays stuck on 1. The script is calling sites_aps_install_package( $session_id, $package_id, $params). $params contains: array( 'main_location' => '', 'main_domain' => $domain, 'main_database_host' => 'localhost', 'main_database_name' => $main_database_name, 'main_database_login' => $main_database_login, 'main_database_password' => $main_database_password, 'admin_name' => $adminstring, 'admin_password' => $testingPassword, 'install' => '0', 'locale' => 'en-US', 'license' => 'on'); with everything getting entered in to aps_instances_settings as expected. I am by no means an accomplished developer, and think I've hit a wall with this one.
