Thanks Michael... I'd forgotten that the server that this site is hosted on is set up to only allow Canadian traffic which would be the issue with you bringing up the page. I'd not considered their could be a script issue in Chrome or Firefox... unfortunately I'm not familiar with Javascript so far so haven't used this area of the browsers
Looks like you're onto something... in Chrome this is the error message that is displayed:
Refused to display 'http://yourwestend.com/wp-content/plugins/advanced-iframe/js/iframe_height.html?height=182&width=939&id=advanced_iframe' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
In Firefox:
Load denied by X-Frame-Options: http://yourwestend.com/wp-content/plugins/advanced-iframe/js/iframe_height.html?height=182&width=939&id=advanced_iframe does not permit cross-origin framing.
I'm not sure about the X-Frame options as I hadn't set them but looks like it defaults to "SAME ORIGIN". I did a little reading on the options and played around with it on the server but looks like the only options that I can set are "SAME ORIGIN" or "DENY" which doesn't seem to make sense to me. I suspect I am missing something obvious but can't seem to find a way to allow the page to be displayed in the plugin. Please let me know if there is any other info I can provide to help.
Thanks,
Greg
