vB 4.1.7, add-on version 2.2.0.

Replying to thread gives this error:

Call to undefined function build_thread_counters()

To fix this:

1. Open product XML, search for:

build_thread_counters($threadinfo['threadid']);

2. Add this ABOVE:

require_once(DIR . '/includes/functions_databuild.php');

NOTE: There are two instances of:

build_thread_counters($threadinfo['threadid']);

Apply fix on both of these.
