Hi chittle, I also ran into this problem and i found this one a bit helpful and it works great,
So here is how to Decode Encoded WordPress Theme Footer
Process 1.
In site’s theme folder find index.php, then find the line that says <?php get_footer(); ?>. Above and below it add special text like this:
<!– Encoded Code Start –>
<?php get_footer(); ?>
<!– Encoded Code End –>
Now visit your site as normal, view page source ( in Firefox Right Click Select -> View Page Source), and copy the HTML between those two markers. Now Find the footer.php in your theme folder, select all existing junk encoded code and replace with the copied code. Remember to insert the before tag.
Simple & Easy.
Process 2.
Use this site, paste your encoded code and decode to base64
and this is the link to that website.
