I’m experiencing the same issue on a fresh WP test install with only FakerPress installed. The error message that appears is empty, too:

I am using Laragon to test locally.
[19-Feb-2018 19:21:51 UTC] PHP Fatal error: Uncaught Error: Class ‘FakerPress\Module\Utils’ not found in D:\laragon\www\wp\wp-content\plugins\fakerpress\modules\user.php:127
Stack trace:

If I disable line 127 in modules/user.php it works fine. And it looks like that variable immediately gets overwritten anyway so it probably isn’t needed?
Here are lines 126 through 129:
$description_size = Variable::super( $request, array( 'description_size' ), FILTER_UNSAFE_RAW, array( 1, 5 ) );
$description_use_html = Utils::instance()->is_truthy( Variable::super( $request, array( 'use_html' ), FILTER_SANITIZE_STRING, 'off' ) );
$description_use_html = Variable::super( $request, array( 'use_html' ), FILTER_SANITIZE_STRING, 'off' ) === 'on';
$description_html_tags = array_map( 'trim', explode( ',', Variable::super( $request, array( 'html_tags' ), FILTER_SANITIZE_STRING ) ) );
Hope that helps. I’m just going to leave that line commented out and probably won’t need FakerPress again until it’s fixed anyway ??
