Hi there!

Could you please help me resolve the issue with shortcode ALWAYS appoearing on top of posts instead of a place i put it to?

if ( !function_exists('navayan_subscribe') ){
		function navayan_subscribe(){
			wp_enqueue_style( '', CONST_NYS_DIR . 'default.css' );

			$wrapper_id = 'ny_subscribe_wrapper';
			echo "<div id='". $wrapper_id ."'>";

			// EXCLUDE SUBSCRIBE FORM FOR LOGGED IN USER
			if ( !is_user_logged_in() ) {
				wp_enqueue_script( CONST_NYS_SLUG, CONST_NYS_DIR .'default.js', array('jquery'), '1.7.2' );

				echo '<p>'. getOption( 'ny_subscribe_field_form_description', __('Know the updates by subscribing') ) .'</p>';

				if ( isset( $_POST['ny_subscribe_submit'] ) ){
					nys_AddSubscriberSubmit ();
				}
				echo "<form class='v". CONST_NYS_VERSION ."' id='ny_subscribe_form' method='post' action='#". $wrapper_id ."'>";

				nys_FormFields();

				echo "<p id='ny_subscribe_submit_wrapper'>
							<input type='submit' name='ny_subscribe_submit' id='ny_subscribe_submit' value='". getOption( 'ny_subscribe_field_label', __('Subscribe') ) ."' />
						</p>
					</form>";
			}else{
				_e( "<p>". getOption( 'ny_subscribe_logged_in_msg', __('Вы уже подписаны!\!') ) ."</p>" );
			}

			echo '</div>';
