To hide tags in any theme for free there are at least two files you must manipulate within your chosen theme.

index.php (home page)
single.php (blog or posts)

1. Open the index.php and the single.php in any text editor and locate this string of tags:

<?php if(function_exists(“the_tags”)) : ?><?php the_tags(‘Tags: ‘) ?><?php endif; ?>

2. Enclose this string of tags within php comments;

<?php /*?><?php if(function_exists(“the_tags”)) : ?><?php the_tags(‘Tags: ‘) ?><?php endif; ?><?php */?>

3. Save the file and replace the old one.

Doing it this way preserves the original data, but does not allow the tags to be viewed.

I hope this helps. I worked like magic for me.
