[Plugin: Twitter Follow Me Box] v1.2 Cannot modify header ERROR

I trouble shoot with all errors on and before I tried out this plugin live I noticed a small error.

On line 12 of tfmb.php file you have a space… this is what it looks like

<?php
/*
Plugin Name: Twitter Follow Me Box
Plugin URI: http://www.geniusdeveloper.com.br/plugins-2/twitter-follow-me-box/?lang=en

?>

<?php
add_action('admin_menu', 'tfmb_add_menu');
add_action('admin_init', 'tfmb_reg_function' );
add_action('wp_head', 'tfmb_add_head');
add_action('init', 'tmfb_reg_jquery');

Notice the gap between ?> and <?php get rid of those lines and make it look like this…

<?php

add_action('admin_menu', 'tfmb_add_menu');
add_action('admin_init', 'tfmb_reg_function' );
add_action('wp_head', 'tfmb_add_head');
add_action('init', 'tmfb_reg_jquery');

This will prevent output to the browser. The error prevents you from changing any settings in the admin…

and also an error on the main site.

Like I said… not a big deal , just a small oversight , although I would recommend testing with all errors on. Great plugin btw!
