The followings steps should be taken when troubleshooting PHP-Nuke after an install.
1. Go over to NukeSupport and search their
forums. Chances are they've seen this problem before and a solution already exists for it.
2. If no solution was found, post a new topic with a brief description of the problem
as the topic title so that an experienced user of Nuke can help you quickly, and other
users of Nuke will be able to find that same problem much more easily if they encounter it.
Note about the Security Codes in Nuke 6.5 The security codes will only show up if the GD extension is enabled in PHP.
