Why do I get an Internal server error when creating database after OpenERP 7 install on Centos ?

I am running a Centos 6.3 server and used the installation script found on the old openerp forum to install OpenERP 7.

After the install, I open OpenERP in the browser and create a new database, after I click the button it opens a popup with the following message :


500 Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

In the terminal, when I run "service openerp start", here's the output I get :

[root@nsxxxxxx openerp]# service openerp start

Démarrage de OpenERP Server Daemon (openerp-server) : [ OK ]

[root@nsxxxxxx openerp]# Traceback (most recent call last):

UnicodeDecodeError: 'utf8' codec can't decode byte 0xab in position 1184: invalid start byte

What can I do to try to fix this error ?

EDIT : Here is the what "locale" returns on the server:

Your error message: UnicodeDecodeError: 'utf8' codec can't decode byte 0xab in position 1184: invalid start byte is about python trying to decode some character, it is expecting it to be UTF8 (Unicode), but it is not. This can happen is you have edited some files on a system which does not run the same kind of OS (Mac, Linux, Windows) as the server.

Another issue might be the usage of accents. Given Démarrage de OpenERP Server Daemon (openerp-server) : [ OK ] , I expect you to be in a french-speaking country. And there they use quite some accents (é or è for example).

Do you get the error with an empty database?

More information about unicode and your errormessage, have a look at the explanation at stackoverflow


After some searching around, I found out that '0xab: ASCII code for Left double angle quotes'. So it loks like that you have modified a file on Windows, and typed ", which has been converted by Windows to the left double angle quotes (can't do it here). Hopefully you have got enough information to fix your issue

Thanks for your answer. The server is on Centos and I connect to it from a Lubuntu box, so the OS is the same kind. I get the error when I push the "Create database" red button. PS. I juste ran the installation script you posted on the question "install-openerp-7-on-red-hat" and I still get the same error after. I'll keep looking.. definetly something to do with encoding.

Weird you run into that issue, while we do not have that. Given the 0xab character, I still expect somehow that the encoding is the issue, as you also found. Did you install CentOS in French? Is there a username/password you use which has accent in it?

I ended up using another install script found on the web, and everything works now (sorry can't post the link due to lack of karma). Still don't know exactly what happened. Thank you anyway for having looked into that.
