Okey I deactivated it and installed WP Fastest Cache instead. The backend is already way faster, but I still struggle with the query string issue and loading time..
removed it – function.php is in it’s original form again
I think it’s your cache.. Just checked on 3 different devices.
Fixed it – adjusted the function.php to:
//* Remove query strings from scripts
function _remove_script_version( $src ){
$parts = explode( '?=', $src );
return $parts[0];
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
