WP-Member plugin error "Are you sure you want to do this?"

It appeared to be a problem with the update itself. We updated the plugin from within WordPress, and it left some files unchanged. Chad Butler was able to identify the issue because he’s familiar with the files and immediately noticed something wasn’t right. He-installing the plugin from scratch which fixed the problem.

Amadain, Chad is releasing a new version of wp-members next week which appears to have some significant changes. It might solve the problem. But in the meantime, here’s a fix he asked me to try that you might be able to try. I couldn’t do it because one of my files hadn’t updated, which made part of the change impossible to attend to:

In wp-members-register.php, line 48 currently is:

check_admin_referer( 'wpmem-register' );

Replace it with this:

if( empty( $_POST ) || !wp_verify_nonce( $_POST['wpmem-form-submit'], 'wpmem-validate-submit' ) ) {
$wpmem_themsg = __( 'There was an error validating the form.', 'wp-members' );
return;
}


In wp-members-dialogs.php, line 333 is:

wp_nonce_field( 'wpmem-register' ) . '

Replace it with this:

wp_nonce_field( 'wpmem-validate-submit', 'wpmem-form-submit' ) . '
