How do I stop the other resellers plans from showing up in everyone's package list? Must be some little checkbox I'm missing somewhere in the acls.

What do you mean? Could you elaborate?

Greetings,
This is normally a problem with your ACL (Access Control List). You will need to edit this (as root) in the "Reseller Center" of WHM

Yep, don't know why I didn't see it before.. Allow use of Global packages in the reseller ACL was left checked for some reason. Fixed.

Ah, I also experienced this same issue with my last host provider before. I could see other resellers plans as well.

So the reason was because that ACL (Access Control List) ?
Thanks for this info.

yes, there's a checkbox the root host can turn off for the access control for your reseller account -- it says something like Allow creation of accounts using Global packages. That checked will end up showing you all of the other plans all other resellers created in addition to your own.. usually not desirable by the host OR the reseller.

Check your ACL list and make sure to uncheck the checkbox that talks about using global pacakges on package list and this will solve you issue.
