Disappearing PM issue

[bucks.ie]

Im using 3.8.2 and recently some of my members have brought to my attention that some of their PM's are disappearing.

They seem to be getting a notification of a PM but when they go to view its not there.

Any idea what could be causing this?

My forum is with Hostgator and the db was down for a bit last week, other than that could a plugin be causing this?

Thanks.

Have you tried looking in the database to see if there really is a new PM for the user?

You could try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

define('DISABLE_HOOKS', true);
