Hello,

I'm currently testing Odoo v9 CE for my society, indeed we need to change our system.

So I installed Odoo on a VPS with Debian 7, and it has been very complicated to install (a lot of dependency issues), they really should update the manual, but now it works.

My collaborator who also tests Odoo told me yesterday that he can't create a new product in the manufacture application, so I'll see, I thought I had not put him the good rights, but no problem.

He receives this error message:

Odoo Warning - Access Error 

The requested operation cannot be completed due to security restrictions. Please contact your system administrator.

(Document type: mail.channel, Operation: read)

After lot of research, I find no information about this, so I decided to reproduce the bug to find a solution.

To reproduce it, you must open twice your account on Odoo and forget to disconnect one. However, this does not help much to resolve the issue.

This error message also appears on the other application for example discuss app.

 sudo service Odoo restart

sudo service postgres restart

This does not solve the problem, and even if it did, I would have to find the source issue, because if you put it in place in the company, we can not afford this kind of problem happens.

Moreover, enable/disable accounts does not change the issue.

I ask you to help me to give some helpt.

Thanks for answering me,
