Hi elliot. I only get the error if I remove the If function exists statement, when it’s put at the end of functions.php as…
if( function_exists('acf_add_options_sub_page') )
{
acf_add_options_sub_page( 'Footer' );
}
No php errors show up, its just that nothing happens.
No spelling mistakes made, just copying and pasting. The options add-on is installed and works fine. Let me know if you need any more details, this is a great plugin.
