Hi Julien,
I’ve installed WP Code Highlight.js plugin and it’s working fine when inserting a [code] shortcode in the ticket body (first message), however Awesome Support seems to strip out the shortcodes from the tickets messages (answers), so we're no longer able to use [code]. However pre and code html tags are working fine.
I would still prefer Awesome Support not to strip out the shortcodes.
Is it possible?
No, it will not be possible. Awesome Support strips shortcodes for security reasons. Sorry about that.
I think it’s safe to allow shortcodes from admin users only.
Thanks, anyway.
Unfortunately it is not. Various user roles can have access to tickets, and if shortcodes were rendered, it could be quite easy for someone to get access to information (s)he was not supposed to.
