Server specs (Server OS / Apache / MySQL / PHP / DragonflyCMS):
I've also had to add Facebook's Open Graph content to the theme's header.html, as Fb in their wisdom have elected to totally ignore it if placed in the body, even though it is required!
I've just stuck it at the end of the head, ie just before the </head> line.
Interested in hearing any 'official' line, but if there's more than just OG to be added, perhaps I'll add a header-3rdparty.html to reDesign, and then <!-- INCLUDE header-3rdparty.html --> in header.html ...
Or just add a Comment - 3rd party stuff goes here?
[PS. It's a real pain in this v10 having to re-open the OP because you can't see the History when posting as you could on v9, v8, PHP-Nuke, etc. And Preview still ignores <br /> ]
