The Bitnami packages are great for getting started with MediaWiki quickly. Yet when something goes wrong, you have a lot of learning to do, such as learning MySql administration. I have a backup of the entire C:\Program Files\Bitnami WAMPStack\ containing the mysql bitnami_mediawiki database. Is there a way to import the old \mysql\data\bitnami_mantis\ folder into a new install of the Bitnami MediaWiki 1.16-2 module? I confess that I messed up and did not make a MySql dump of the bitnami_mediawiki MySql backup. I thought a directory backup would be good enough. I tried copying the bitnami_mediawiki database, restoring the original LocalSettings.ph, and running update.php but I get an exception when trying to create table interwiki as pasted below.
