Quote from: Bruno17 at Sep 18, 2014, 11:12 PMhow is the contact-form-chunk implemented in your template?
The master template has a [[$Header]] chunk (contains nav bar, etc) and the contact form chunk is called as:
<div id="popupContactForm" class="popup-inline-content">
<div class="row">
[[$contactForm? &idSuffix=`Modal`]]
</div>
</div>
to create a popup/modal form on every page.
The Contact Us page resource also uses the form chunk to include a non modal version of the contact form:
<div class="col-md-4">
<a name="contact" class="anchor"></a>
[[$contactForm]]
</div>
It's on this page that the issue occurs, when idSuffix is
null
Be glad to post more info if you need...
