Hello,
I've created a form on the page: http://chillamor.com/nl/voorbeeld/formulieren/about/
When submitting this form, it seems that nothing happens. A small rotating image is shown which means that the form is being processed. This rotating image does not disappear, so it seems that the form 'hangs'. However, when I close the page manually, I'll see that the information is stored in the back-end of my WordPress site. Any idea why the form is not processed normally?
