I have installed Docebo and I have begin configuration, but when I go to http://www.mydomain.com/doceboCms/ it appears the follow message:
"Usted no está autorizado para acceder a esta página."
and I can't configurate anything in this section.

( I have access to DoceboCore section and I can configurate at this section)

hello,
this is a frequently asked question: you first have to setup and publish some pages from the admin area (doceboCore) of the cms.

Please also note that from the upcoming docebo 4.0 the cms won't be officialy supported anymore.

bye,
Giovanni.
