I have a form embedded via the widget in a sidebar. On some (very few) pages displaying a custom post type, I end up with this in the source:
[html] <iframe id="gform_ajax_frame_1" name="gform_ajax_frame_1" src="about:blank" style="display:none;width:0px; height:0px;"> <html> <head></head> <body></body> </html> </iframe>
This is an exception, because most pages displaying the same custom post type work just fine.
Example of problem: http://www.johnmurray-realtor.com/communities/va-aldie-creighton-farms/
It's not something I knowingly put there by a setting. Can someone explain why it's there and what controls it? I have a separate script that I wrote that emails me when a user encounters a bad link on my site. On this page, I get an email because of the about:blank, but I don't get the email on other pages with the same sidebar widget, where the iframe code is not in the page source.
I'm running the latest stable release of the GF, 220.127.116.11.
Thanks in advance.
