XF 1.2 Stumbleupon + xenforo = white screen

[imsory]

Hello, I found a bug. If you add a link to stumbleupon then you get a white screen. I think this bug appeared after the upgrade to version 1.2.x.
Example:

If you think this is a legitimate bug, you should make a thread in XenForo Bug Reports.

It's not a bug. By default, XenForo cannot be embedded in an <iframe> to prevent clickjacking issues. This can be disabled by editing config.php if you really need it.

Thank you. What I need to add to config.php? Can I turn it on only for SU?

No, if you want it to show on stumble upon, you'll need it enabled for everyone:

Look for clickjacking.
