Still Receiving HTTP 500 error

Howdy,
I used the file that was previously packaged in the forum, blackfyre_custom_post_types16-1, after the updates to the theme didn’t fix the 500 error. The following is what I found in the log file.

PHP Fatal error: Uncaught Error: Call to undefined function phpremove_shortcode() in /home2/gigemgam/public_html/wp-content/plugins/blackfyre_custom_post_types/bootstrap-carousel.php:1
Stack trace:

#5 {main}

Any help in correcting would be greatly appreciated
