Quota Setup Problem

Hello all i recently purchased a whmcs/whm/cpanel license to manage my products easier, and i m stuck with something I correctly setup my package and my whmcs module to create the account instantly after payment but i am stuck for one detail, the disk space usage and limit, all other limits such as email account ftp account works correctly, but for disk space it goes allways back to unlimited, even after i changed manualy the disk space, is this a bug or am i missing something ? I tryed already this command but doesnt resolve anything /scripts/fixquotas Installing Default Quota Databases......Done journaled quota support: not available with vzaquota (disabled) checking out /backup checking out /backup Quotas have been enabled, however they may not be up to date as quotacheck has been skipped.
