(run the following as a user with root/sudo access)
df /home (this will tell you where /home is mounted)
quotacheck -cugvmf -F vfsv0 /<wherever /home is mounted> (to rebuild quotas)
/home/interworx/cron/storage.pex (to force iworx to rerun the storage cron and update the information)
Also, verify that the entry in iworx.ini under [quota] is set to where /home is mounted.
If this doesn’t solve the problem, please open a support ticket and we’ll get it taken care of.
