Description

One of the 2 thousand URLs with the problem:
http://www.oceanexpert.net/viewMemberRecord.php?&memberID=20045

The piece of HTML creating the problem seems to be:
<h1>
Details of<span itemprop="name"> <span itemprop="honorificPrefix"></span> <span itemprop="givenName">Laury</span>  <span itemprop="familyName">Miller</span></span>
</h1>
(this may disappear as we may workaround the problem)

Error message:
Internal error.
