To make posts display well when sharing on Facebook, it makes sense to set up OG tags.  I know what to add... probably best done using the Header Injection, but I can't find a list of tags I can insert. I assume there are some, somewhere? Assuming someone can tell me where the tags are, here's how to inject OpenGraph tags... (Remove the preceding asterisks... I put them in to help Una accept the example)

*<meta property="og:url"                content="???" />*<meta property="og:type"               content="article" />*<meta property="og:title"              content="???" />*<meta property="og:description"        content="???" />*<meta property="og:image"              content="???.jpg" />

Can anyone point me to a list of Dynamic variables I can replace the question marks with that I can use?

A screenshot works fine on Una.io... why isn't it visible on my site? (See screenshot). I assume it is just a permission somewhere?

The server audit says:

disable_functions = exec,passthru,shell_exec,system - FAIL (must be without shell_exec,eval,assert,phpinfo,getenv,ini_set,mail,fsockopen,chmod,parse_ini_ 

Things seem to be working, but why do I need to disable these and how how I do that? (CPanel)?
