iFrame stopped working today.

Hello,

My iframe stopped working today. You can see it live here: http://www.epfirst.com/find-a-doctor/

And here’s the code I’m using:

[iframe src=”http://www.epfirst.com/EP1Cust/Directorysearch.asp” width=”100%” height=”600″ scrolling=”no”]

The “find a doctor” and the “find a pharmacy” pages are not working. They return a 404 message within the iframe but the individual pages work fine outside of wordpress. Nothing changed, no updates or installs of any kind. Just simply stopped working.

Please advice. Thanks!
Perla
