It seems that WHMCS doesn't pass the package name to my WHM/Cpanel correctly.
If i give access to the Cpanel reseller to create package, each time WHMCS will pass the package name as "default", so cpanel created the account under the package "default"
If i turn off the access to create package of the cpanel reseller.
Then when order completed, there will be erro as below:
Module Create Failed - Service ID: 42 - Error: Sorry, you must choose a plan
I have specified the correct package name in Modues setting, but it still told me i have to choose a plan.
Please help.
