PHP error after updating site. Whole site down.

I tried to update my theme. I followed the direction on here and now have this error:

Warning: require_once(/home4/techedup/public_html/esportsforedu/wp-content/plugins/blackfyre_custom_post_types/bootstrap-carousel.php): failed to open stream: No such file or directory in /home4/techedup/public_html/esportsforedu/wp-content/themes/blackfyre/functions.php on line 23

Fatal error: require_once(): Failed opening required ‘/home4/techedup/public_html/esportsforedu/wp-content/plugins/blackfyre_custom_post_types/bootstrap-carousel.php’ (include_path=’.:/opt/php70/lib/php’) in /home4/techedup/public_html/esportsforedu/wp-content/themes/blackfyre/functions.php on line 23

The entire site is down and I can’t even login to wp-admin.

Please advise.
