I got the following error after installation - Fatal error: Call to undefined function transact() in /var/zpanel/hostdata/arawakcity/public_html/arawakcity_org/profiles/cforge/modules/mutual_credit/mcapi.inc on line 553

I fixed it through installing the latest Dev version of the mutual credit module from here - http://drupal.org/project/mutual_credit

To do this unpack the dev tar into /profiles/cforge/modules and run install.php and the site should come up.

It appears the latest version wasn't added to the distribution when it was packaged.
