I installed vestacp and whmcs on an ubuntu 16.04 vps.
When I want to order a free hosting on whmcs with a package created "default1".
my order is pending. I will see on the admin panel and I decide to pass it in active. this is the result.
I decide to delete the user created on vestacp when I placed my order.
and I redo the manipulation.
you have an idea of the solution?
ps: I took this module to do the link.
the "default" package works ...
