(1) Per the directions, I unzipped and uploaded the plugin to the correct folder on my server.
(2) I clicked on Activate - I get this error -
Warning: require_once(membershipincludes/classes/class.membership.php) [function.require-once]: failed to open stream: No such file or directory in /hermes/bosweb/web051/b513/nf.nyghtfalcon/public_html/Test2/wp-content/plugins/membership/membership.php on line 43
Line 43 is a reference to the class.subscription.php file - and it is exactly where it needs to be.
How do I resolve this?
