Support › Meta Box AIO › Fatal error: Uncaught Error: Class 'MBBParser\Parsers\MetaBox' not foundResolved
I have installed MetaBox AIO. Since the latest update to 5.3.3 I am not able to add or edit Custom Field Types via the Builder anymore. I am getting this error message:
Fatal error: Uncaught Error: Class 'MBBParser\Parsers\MetaBox' not found
in xxx/wp-content/plugins/meta-box-aio/vendor/meta-box/meta-box-builder/src/Edit.php on line 180
Call stack:
MBB\Edit::update_meta_box()
wp-includes/class-wp-hook.php:289
WP_Hook::apply_filters()
wp-includes/plugin.php:206

wp_insert_post()
wp-includes/post.php:4354
wp_update_post()
wp-admin/includes/post.php:419
edit_post()
wp-admin/post.php:227
When digging into the Code, this is the problematic line of code:
$parser = new \MBBParser\Parsers\MetaBox( $settings );
The class does not seem to exist.
I've just started getting this error today as well. Any time I try to edit something with the Meta Box Custom Field builder in WordPress I get an error.

Thank you.
Hi Long.

Hi,
Refer to this topic https://support.metabox.io/topic/uncaught-error-class-mbbparserparsersmetabox-not-found/.
Please try to re-install the plugin Meta Box AIO which downloaded from the My Account page then check the issue again.
Thank you Long, this worked. No idea why - but it did. Great
