-2

adding a simple FB tab. works well with one url but shows blank page with another. Both are the same, both are HTTPS.

  1. https://www.chirva.com/stuff/ - works
  2. https://www.mchelper.com/fb_contact/ - returns blank page

both have identical settings on FB side. Same tab/canvas details (only URLs are different). Can it be on hoster's side? (something like "protected from embedding" )

Please have a look at a test page where I tried to embed both URLs http://a5w.org/mch/ as you can see - the first one won't load. why???

$url = "https://www.mchelper.com/fb_contact/";
$header = get_headers($url, 1);
echo $header["X-Frame-Options"];

(returns "SAMEORIGIN" which means - the page won't load in iframe)

That's what I wanted to know

and here is how to "fight" that:

Header always unset X-Frame-Options

to your.htaccess file in order to disable X-Frame-Options.
