Error when submitting "existing" email address (500 error!)


Hello, many of our customers will subscribe to a list multiple times. Because of the volume we do, it's really important they are redirected to the "Sub. exists redirect" value in the list settings.

I'm testing this, and I always get a 500 error page from MailWiz, and this text:

Error 500!
Trying to get property 'customer_uid' of non-object

The expected behavior is that - since the email address is already subscribed to the list, mailwizz will redirect the subscriber to the "Sub. exists redirect" in the form settings. We have it setup like this:[RESULTSLINKURL]&name=[FNAME]

This is happening on the same exact form the customer had just submitted.

It looks like this:

<form name="form1" id="form1" method="post" action="" onsubmit="return aweberformcheck1();">
<input id="FNAME" style="" type="hidden" name="FNAME" value="Dan" />
<input id="RESULTSLINK" type="hidden" name="RESULTSLINK" value="test/report.php?b=12&p=yes&s=1&a=other&f=yes&dr=yes&t=" />
<input id="INTEREST" type="hidden" name="INTEREST" value="other" />
<input id="ASTROLOGYSIGN" type="hidden" name="SIGN" value="12" />
<input id="RESULTSLINKURL" type="hidden" name="RESULTSLINKURL" value="test/t-report.php?b=12&p=yes&s=1&a=other&f=yes&dr=yes&t=" />
<p> </p>
<div style="width:500px; margin-left:auto; margin-right:auto; text-align:center">
<label for="text">Your Best Email Address:</label>
<input id="EMAIL" style="" type="text" name="EMAIL" value="" />
<br />
<br />
<input name="yt0" type="submit" class="submit" id="button" value="Continue" />


Any help would be greatly appreciated! Thank you!
