hi i would like to purchase the premium softaculous plan for my cpanel account. but i am not sure if my cpanel account has to be the same as my softaculous account. how are they linked?
It looks like the Softaculous license on your server is Free version hence you need to upgrade to premium version as WordPress is available only in the premium version.
You can create a separate account on Softaculous website as it does not need to be linked to your cPanel account. You just need to update the license key on your cPanel account after you have purchased it.
In case you have a VPS or dedicated server and want to use Softaculous on all the cPanel accounts on the server you can purchase the server license here :
