Hi @eumat,
There are two options, each with a couple of discussions in the forum:
- Change the old administrator’s account and continue using it (see e.g. https://pkp.sfu.ca/support/forum/viewtopic.php?f=8&t=6582)
- Create another administrator account
I suspect the first is the best option. Note that the SQL queries in the above link assume MD5 encryption; you’ll likely be using SHA1 encryption. You can check the encryption setting in your config.inc.php to be sure.
