Hi I create Metabox Settings Page and Elementor Integrator. But the value not showing.
Yhen I try Metabox at post / page and use Elementor Integrator, it shows the value.
So I think there is bug for MB Settings Page.
This is an issue for me as well. The error comes from GroupField.php on line 257 according to the error message. Any patch that can be applied? My entire site is built on this and therefore non-functioning at the moment.
