The final production release of WP-Members 2.8.0 went out with a small bug in the auto excerpt feature. This causes the default (more…) link to show on every post, even when the auto excerpt feature is not enabled.
A patch has been applied to the responsitory download already. However, the first 800 or so downloads of the upgrade contain the bug.
Fixing the issue is relatively simple, so you can either apply the fix yourself, download the corrected file from here or the subversion repository, or redownload the plugin and reinstall.
If you want to apply the fix yourself, you need to change line 970 of wp-members-core.php from this:
if( ! $more ) {to this:
if( ! $more && ( $arr['auto_ex'] == true ) ) {2.8.0 has been updated in the repository here: http://wordpress.org/extend/plugins/wp-members/developers/
You can download the entire zip, or select svn to go to the subversion responsitory and download just wp-members-core.php.
