Incompatible with GravityForms – solution available

This plugin breaks GravityForms downloading form-uploads.

solution: add this to your theme, or an mu-plugin;

// Fix GF downloads with minify-html plugin.
add_filter( 'gform_permission_granted_pre_download', 'myprefix_fix_gf_download', 10 );
function myprefix_fix_gf_download( $permission_granted__passthru ) {
	while ( ob_get_level() ) {
		ob_end_clean();
	}

	return $permission_granted__passthru;
}

This will close the problematic output buffer that is started by the plugin (and any and all other output buffers, which is good because we want to send a binary stream)
