Test form vs. real life

We have built a form with email and database actions. When I click "Test Form" in Chronoforms edit mode it works fine, but when called in a webpage it fails on Submit and returns to the filled out form. No debug message displayed.
The page also contains some HTML, but I tried to delete it and it made no difference:
[Chronoforms5 chronoform="BILLETTER"]
<div class="gbs3">
<div class="chrono-page-container">
<div class="container">
<div class="row"><form id="admin_form" action="http://www2.hvasnet.dk/wp-admin/index.php?page=Chronoforms5" method="post" name="admin_form">
<div class="panel panel-default gcore-black-text"></div>
</form></div>
</div>
</div>
</div>

The page is http://www.hvasnet.dk/www/?page_id=66
I also attach the form[attachment=0]CFV5_FormsBackup_ON_http---www.hvasnet.dk_10_Apr_2015_04-11-23.cf5bak[/attachment]

Hi HVASnet,

Please try to download the latest update and install over yours, does it fix the issue ?

I have updated to CF5.0.9 on WP4.2.1 and the problem persists

Hi HVASnet,

I have just tested your form on a test website here and it worked fine, could you please try it on a new WP install on the same server if possible ? and please let me know the results.

Regards,
Max

I have this same problem. What was the resolution?

Is this a new WP install ?

It's a new Joomla install.

Hi pschmehl,

You have posted in the ChronoForms for WordPress forum so there may be a little confusion.
