Remove Wp Super Cache Html comment in footer

In themes functions file add

// Remove unwanted HTML comments
function remove_html_comments($content = '') {
	return preg_replace('/<!--(.|\s)*?-->/', '', $content);
}

Hi,

thanks for the help i used your code but still shows!

I don’t use this solution myself, I have google pagespeed on my server with a filter that removes html comments. But unless you have root access to your server this isn’t possible.

All you need is a plugin or some functions code that will remove html comments.

Hmm talking about Pagespeed is it really speeding your website ?

I found solution :

Try the dev version, I added an option on the Debug page that disables these messages completely.

Great

It does although the main boost comes from deferring javascript and converting images from jpg to webp on the fly. Both of which can be achieved by simpler means.

Most of the other filters have a minimal effect to be honest. Deferring javascript can also mess up your site in some browsers so needs thorough testing.

Goto Debug tab on https://yourwebsite.com/wp-admin/options-general.php?page=wpsupercache&tab=debug and uncheck below option:
