Hello Sander, Well thanks a lot for your reply. You are right, I guess it is a database issue. In fact I got the Koha 3.8 version from this link: http://download.koha-community.org/koha-3.08.10.tar.gz. Someone helped me installing it. Can you please just explain to me how can I delete the database and make a new one and use the Web Interface to redo the installation and from where I can install all the samples? Thanks again.

Do you perform a new installation? If yes you can try to delete the database and make a new one, then redo the installation of Koha via the Web Interface, and install all the samples (framework, patron, etc...).
