It sounds like you used the Manage Domains section here to add redirection, and now the entire site is gone since you removed the redirection. Does your domain still show up in Manage Domains? It should show up as Fully Hosted. You only get one choice in Manage Domains for how your site responds. You can’t have Fully Hosted and Redirected.
If your site is still in /foro, then you should Edit your Fully Hosted Domain so it uses /home/USER/laionia.com/foro as its web directory.
