Log into your WP Dashboard, and go to the Plugins menu. Find s2Member in the list of plugins, and click "Activate".
If that does not do the trick, try disabling other plugins until the s2Member menu re-appears. Sometimes other plugins conflict with the positioning of the s2Member menu; overriding s2Member completely, which causes the s2Member menu to be hidden.
@C/TODO: the s2Member menu was pushed up in v3.0.6+, so that it sits just beneath the Users menu in WordPress. This will be reverted back in the next release, because it causes conflicts such as the one being reported here.Statistics: Posted by Jason Caldwell — June 23rd, 2010, 1:45 pm
