Hi Mark
I have been speaking with the theme developer and;
Short answer: Putting some content in the excerpt field gets the form visible on the page
Detailed answer: https://github.com/highrisedigital/wpbroadbean/blob/master/inc/functions.php#L416 the plugins is using include_once to render the form
The theme uses get_excepts function to generate open graph descriptions, this function calls the_content filter, so the view already called once and return empty results when page content generated, as workaround, I can fill in the excerpts so the the_content will be called only once.
As the jobs are filled dynamically through the feed, I am not sure how to circumvent this.
