Hello,
We have just checked out your Forms and there is some PHP error in the include/form.php File.
Double Check your PHP Codes or Customizations made in this File. If you are still facing further issues, then please consider adding the .customjs Class to the .form-widget DIV and then the following code at the very top (just after the PHP open tag) of your File:
[ch_pre]error_reporting(E_ALL);[/ch_pre]
which should display all the possible errors. Please notify us about the Error Message you see, after going through the process above, so that we can provide you with more assistance on this.
Thanks for your Patience.
Meanwhile, do let us know if we can help you with anything else or if you find any further issues with Canvas.
