niche site template broken

Hi there,

Niche uses a couple of Hook Elements that use PHP.
That 'error' is because your server config is set to DISALLOW FILE EDITING ( more info here )

The simplest fix is to enable PHP Editing in the GP Hooks by adding this PHP Snippet to your site:

add_filter( 'generate_hooks_execute_php', '__return_true' );

Adding PHP:

Sorry to raise an old thread from the grave but it was exactly my issue except I also wanted to add it to the main page. I forgot to click "execute PHP" on the new element. The PHP snippet posted above worked perfectly.

Glad to hear you found the solution you needed!
