Warning: Illegal string offset 'id'

can you provide details through our contact page? This is more than likely the type of server that your site is in.

Glad that you worked it out. For others that are having similar warning. Open wp-content/plugins/gift-certificates-lite/gift-certificate-lite.php

check the following line

$id = intval($_atts[“id”]); and replace it with

//$id = intval($_atts[“id”]);
