  • I’m writing a plugin with similar following codes:

    add_filter( 'the_content' , 'my_function' );
    function my_function( $content ) {
    	$test_config['timeframe'] = '7d';
    	update_option('test_config',$test_config);
    	return $content;
    }

    It works well on my computer local test, but when I upload it to the server, it refuse to work.

    I tried add_action(‘wp_head’, ‘my_function’), it works.

    Any help?

    Thanks.
