Iframe not loading

Hi athemes,
First, thank you for the great theme.
My website (www.medischbenefietfriesland.nl) has a page to buy tickets from a ticketcompany (http://www.medischbenefietfriesland.nl/kaartverkoop/). This includes an iframe:
<iframe src="https://www.ticketkantoor.nl/shop/MBF2016&embed=1" name="ticketshop" width="500" height="600" frameborder="0"</iframe>

When trying to load the page only the bubble shows up. I tried different browsers.
The page is set up like: page, 2 rows, 1 with visual editor widget and 1 with a text widget. That’s it. When I remove the iframe the page loads fine. I tried to put the iframe in between divs but that did not work.

Thanks for any help!

Hello there,

Please note that we are not in position to provide support for 3rd party plugins / scripts. Loading this page trough iframe is causing conflict with theme preloader, so you should be able to disable loading animation by adding custom css code below:

.preloader {
    display: none;

Apply the code trough child theme style.css file or with some plugin, like this one https://wordpress.org/plugins/simple-custom-css/

All the Best!

Thank you very much!
I completely understand that you can’t support 3th party plugins!
