Plugin(s) not longer working or maintained.

Just updated With the “Pirate” filter activated I’m seeing this:

Fatal error: Call to undefined function filter_cdata_content() in /home/macypest/public_html/blog/wp-content/plugins/text-filter-suite/tfs-pirate.php on line 20

This is on a client site here:
https://www.macyspestcontrol.com/blog/like-us-on-facebook-and-you-could-win-a-25-starbucks-card/

It’s not happening on some other sites where I have the plugin installed. Might you have any pointers for me?

Thanks!!
