How can I update stats for my account on VPS?

f you are on a cpanel vps, the stats should be automatically updated on daily basis. If somehow they are not getting updated, please make sure the account is within the allowed disk quota. You can check this from WHM.

In case you need to update the stats manually, you can do this via ssh using this command format:

/scripts/runweblogs USERID

where USERID is the account username.
