Importing from Burning Board 2.3

  • Hello!


    I'm finally updating my old Burning Board (2.3.5, actually) - to 4.0.8. I was able to install and begin a data import from my old site, but the import quickly failed.



    I did receive a warning during installation:
    The MySQL configuration option “innodb_flush_log_at_trx_commit” is set to “1”, slowing down certain database queries. It is highly recommended to set it’s value to “2”.


    When I attempt the data import, I get the following PHP Error Message:


    Error Message
    PHP notice in file /home/mcshaffr/public_html/GameCode/wcf/lib/system/exporter/WBB2xExporter.class.php (211): Undefined index: grouptype


    Stacktrace:

    #10 {main}


    I was able to help a friend of mine update his old 2.3.6 site to v4, so I've actually gone through the entire data import process successfully before - but this error has me stumped.


    Thanks for any help you can give.
