No form is shown when clicking on link in admin

I have been using this excellent component for a long time a couple of website and never had any problems with it 🙂

I installed it on a new website yesterday, I copied the form code from a working form (chronoforms) and is having a very strange problem.
When I click on the "Link" tab, to see the form in action, I only get a blank page in a new window. No errors, even when I have debug mode on. And yes, the form is published.

I have tried with different versions of Chronoforms, with different form code and get the same problem. No form is shown, just a blank page.

What can this be? There form is supposed to be shown here:

I run this joomlainstallation in the same evrionment as the sites with the working forms.

Hi bandola,

A completely blank page like that is usually a sign of a Fatal PHP error,

Please turn Error Reporting to Maximum in the site Global Configuration and hopefully you'll see an error message that will help pin down the bug.

Thank you for your support.

I turned on the maxium error and got this message when I tried to open the form:
Fatal error: Class 'JDate' not found in /www/webvol6/yf/zdmhl1adf925149/coachgarden.com/public_html/modules/mod_placehere/helper.php on line 72
So, there seems to be a conflict with the module (mod_placehere). When I disable it, the form works 🙂
But i really need this module too. How can I avoid this conflict? I tried to uncomment line 72 in the module, but that just messed up the module.

Hi Bandola,

Is the form on-line so we can take a look?

What content do you have in the PlaceHere module?
