Disable the W3 Total Cache Footer Comment

Most of the WordPress/ClassicPress websites I work on use Cloudflare I don’t often have problems with the W3 Total Cache footer comments in the footer. Cloudflare usually just removes them. But recently I was helping a friend with a website that had the W3 Total Cache plugin installed and the footer comments were being inserted. They simply wanted to get rid of them. Thankfully a quick Google search lead me to a WordPress support comment with the solution.

Add the following code to your theme functions file, or a site specific plugin and you can easily turn off the W3 Total Cache footer comments for all visitors to your website.

add_filter( 'w3tc_can_print_comment', function( $w3tc_setting ) { return false; }, 10, 1 );
