Missing ADODB-InnoDB.inc.pcp


I am busy migrating our OJS installation to a new server and upgrading it from 2.3.8 to 3.0 as well. I have started by installing 2.3.8 on the new server and migrated the DB and the file store. However, when I go to the site on localhost I get the following error message:

Missing file: C:\Program Files (x86)\Ampps\www\ojs\lib\pkp\lib\adodb/drivers/adodb-innodb.inc.php
ADONewConnection: Unable to load database driver ‘’

I have checked the folder and there is no such file. I don’t seem to be able to find one anywhere, including Github.


Hi @Manutius,

Can you double-check your config.inc.php parameters? I suspect you’ve named innodb as your database driver, when it should be mysql or mysqli.
