I have a doubt, i installed the community version of Odoo 10 to start getting to know it, But I never got a message or something to tell me if that was going to work for a period of time, so yesterday, I tried to log in on the instance that i have installed and everything was gone, I can't see the apps bar on top of the page, neither on the left bar side, all the information was lost. Could somone tell me if the community version it work for free for a period of time? or its an error that i got on the instance.
