Reply To: acf-json files not being created

I’m stumped as well. Not knowing what could cause this I would start outputting debugging information by following the code in ACF and and making changes.

For example the ftil /includes/local-json.php line ~205 the function save_json, the following are some of the things I would do. Please note that only one of these would work at a time and would prevent the saving.

public function save_file( $key, $field_group ) {
		$path = acf_get_setting( 'save_json' );

// see what the path is
echo $path; die;
		$file = untrailingslashit( $path ) . '/' . $key . '.json';
		if( !is_writable($path) ) {
// folder not writable
echo 'path is not writable'; die;
			return false;
		}
		
		// Append modified time.
		if( $field_group['ID'] ) {
			$field_group['modified'] = get_post_modified_time( 'U', true, $field_group['ID'] );
		} else {
			$field_group['modified'] = strtotime();
		}
		
		// Prepare for export.
		$field_group = acf_prepare_field_group_for_export( $field_group );

// see what the field group looks like
echo '<pre>'; print_r($field_group); die;
		
		// Save and return true if bytes were written.
		$result = file_put_contents( $file, acf_json_encode( $field_group ) );

// see what is returned by file_put_contents()
echo '<pre>'; var_dump($result); die;
		return is_int( $result );
	}

Depending on my debugging here I would move to either on to other functions, either those called by this function or I’d look for where this function is called.
