Hi @brc

Hmmm… It seems like there is already an admin user in your OJS database. Could you take a look in your database table users? Did you maybe try to do the installation several times i.e. could it be that first something went wrong? Maybe you should drop that database, create a new one and start a clean installation again?

Best,

Hi @brc

Hmmm… I have no idea how is then this possible :-\

The admin user is created and inserted in this function pkp-lib/PKPInstall.inc.php at ojs-3_0_2-0 · pkp/pkp-lib · GitHub that is called here ojs/install.xml at ojs-3_0_2-0 · pkp/ojs · GitHub.
And this happens only once…

Do you create the empty DB for OJS before the installation start or do you let the OJS create the DB?
