Footer Showing HTML tags

Somehow, the theme is now showing the HTML syntax coding I inserted into the Footer Content box under Theme Options.

Before it did not, any HTML tags used in the box worked well and the theme did not show the HTML tags. Then somewhere along the way, it broke and now shows the HTML tags (syntax).

The Tags still work, for example a link still shows as a link, but also shows every tag used to create that footer text & link.

Where can I fix this?

Note: on the ISIS theme website, in the comments area the theme author said to go to “footer.php” and insert:

< ?php echo html_entity_decode ( of_get_option('footer_textarea')); ?>

into footer.php right after;

< ?php echo esc_textarea ( of_get_option('footer_textarea')); ?>

I checked the footer.php and the PHP coding is already there as described above, yet it is not working.
