Disk quota error

I am using API to add a website with

PHP:

$params_website = array('server_id' => 1, 
                            'ip_address' => '*', 
                            'domain' => $myusername.'.remcycle.net', 
                            'type' => 'vhost', 
                            'parent_domain_id' => '', 
                            'vhost_type' => 'name', 
                            'hd_quota' => '-1', 
                            'traffic_quota' => '1000', 
                            'cgi' =>'y', 
                            'ssi' =>'y', 
                            'suexec' =>'y', 
                            'errordocs' =>'1', 
                            'subdomain' =>'www', 
                            'ssl' =>'n', 
                            'php' =>"mod", 
                            'ruby' =>'y', 
                            'active' =>'y', 
                            'redirect_type' =>'no', 
                            'redirect_path' =>'', 
                            'ssl_state' =>'', 
                            'ssl_organisation' =>'', 
                            'ssl_organisation_unit' =>'', 
                            'ssl_country' =>'', 
                            'ssl_domain' => $myusername.'.remcycle.net', 
                            'ssl_request' =>'', 
                            'ssl_cert' =>'', 
                            'ssl_bundle' =>'', 
                            'ssl_action' =>'', 
                            //'stats_password' =>$mypassword, 
                            'stats_password' =>'', 
                            'stats_type' =>'webalizer', 
                            'backup_interval' =>'daily', 
                            'backup_copies' =>'7', 
                            'document_root' =>'/var/www/clients/client'.$client_id.'/web'.$domain_id, 
                            'system_user' =>'web'.$domain_id, 
                            'system_group' =>'client'.$client_id, 
                            'allow_override' =>'All', 
                            'php_open_basedir' =>'/var/www/clients/client'.$client_id.'/web'.$domain_id.'/web:/var/www/clients/client'.$client_id.'/web'.$domain_id.'/tmp:/var/www/'.                            $myusername.'.remcycle.net/web:/srv/www/'.$myusername.'.remcycle.net/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin', 
                            'custom_php_ini' =>'',  
                            'apache_directives' => '<Directory />
                                        Options FollowSymLinks
                                        AllowOverride All
                                        Order allow,deny
                                        Allow from all
                                        </Directory>', 
                            'client_group_id' =>$client_id +1
                            ); 
    
    $website_id = $client->sites_web_domain_add($session_id, $client_id, $params_website); 

As you can see the disk quota is -1 meaning infinite amount of space. When the client logs into ispconfig control panel and looks at the web site he sees -1 as his disk quota. When he click on any of the tabs to get to redirect, ssl, or options it give the error

And then changes the qouta to 0.

The user can also use FTP to add files to his website, so I am unsure as to why this error is occurring.

Any Suggestions?
