PHP Error

I am seeing the following error repeated many times in my PHP log.

PHP Warning: implode(): Invalid arguments passed in /home/…/public_html/wp-content/themes/customizr/inc/czr-front.php on line 4055

PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

Don’t notice any website issues but it is filling up the log with these errors.
