Not working with Caching Plugin

Hi!

I had the same issue. Followed this link and added ‘showhide_toggle’ to the WP Rocket Inline Exclusion list.

https://docs.wp-rocket.me/article/976-exclude-files-from-defer-js

add_filter( 'rocket_defer_inline_exclusions', function( $inline_exclusions_list ) {
	$inline_exclusions_list[] = 'showhide_toggle';
	return $inline_exclusions_list;
} );

Hope it helps. Worked for me at least
