You need to fix this plugin until official patch/version comes out.
1) In file /includes/pipe.php add this below function collect_befores
function collect_afters() {
$afters = array();
foreach ( $this->pipes as $pipe ) {
$afters[] = $pipe->after;
}
return $afters;
}
2) in file /includes/shortcodes.php around line 122 replace whole block to look like this
if ( WPCF7_USE_PIPE ) {
$pipes = new WPCF7_Pipes( $scanned_tag['raw_values'] );
$scanned_tag['values'] = $pipes->collect_befores();
$scanned_tag['pipes'] = $pipes;
$scanned_tag['labels'] = $pipes->collect_afters();
} else {
$scanned_tag['values'] = $scanned_tag['raw_values'];
$scanned_tag['labels'] = $scanned_tag['values']; // <-- this was below if block, delete it there
}
