Hi compacta1200,
If only upload the folder htdocs in meudominio.com.br the path will be meudominio.com.br/htdocs/
1.) Create the folder documents meudominio.com.br/htdocs/documents
The web server must have write permission into this directory
If you have it in meudominio.com.br/dolibarr/htdocs/
then create it in meudominio.com.br/dolibarr/htdocs/documents
See here http://wiki.dolibarr.org/index.php/Installation_-Upgrade#On_a_mutualized_Web_Hosting_Provider.28with_restricted_access.29
And Good Luck
