Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
Recently I encouter an new error I can't say whether its an eror or any congifuration issue but when I updated by odoo 8 server to new stable build css and js of odoo are not loading specially when odoo is deploy using wsgi previously with my old odoo installation it was working properly.
Same issue when I run odoo 8 with gunicorn
gunicorn openerp:service.wsgi_server.application -c openerp-wsgi.py
