Hi,

If Odoo isn't working, first verify your subscription status by logging into your Odoo.com account and checking the "Subscriptions" section for any issues like payment failures or expiration. If your subscription is active, ensure it's linked to your database. For Odoo Online, this usually happens automatically, but for on-premise installations, you need to enter your Enterprise license key in Settings > General Settings.

If problems persist, contact Odoo Support via odoo.com/help, providing your account email, database name, and a detailed description of the issue. Remember that Odoo Community Edition doesn't involve a paid subscription, and you're responsible for its hosting and maintenance. If your subscription has expired, Odoo might suspend or eventually delete your database.

Hope it helps
