Still it shows error

Hi. I had the problem. After having installed "python-passlib python-pil" modules and change the name of the database, it works.

Just Clear Your Browser History.

Than Do Server restart process With Terminal

And Reload Page 

Hi...

I think you need to install python dependency modules, like decortors , & requests etc.. [Check in the console/log]

Me had the same problem, after installing those dependency modules,  Odoo 8 is working fine for me

Hi, 

1. check have you installed "pypdf" package along with decorator and request.

2. clear recent browse history, cookies.
