I use Metabox with Metabox plugin and use primarily Metabox AIO for that. I was facing a lot of fatar error issue while using Metabox Group addon with Elementor.
Error used to be like this:
An error of type E_ERROR was caused in line 288 of the file /var/www/domain.com/htdocs/wp-content/plugins/meta-box-aio/vendor/meta-box/mb-elementor-integrator/src/GroupField.php. Error message: Uncaught TypeError: array_column(): Argument #1 ($array) must be of type array, null given in /var/www/domain.com/htdocs/wp-content/plugins/meta-box-aio/vendor/meta-box/mb-elementor-integrator/src/GroupField.php:288
To resolve this, I trying researching about Metabox Elementor Integration. I was surprised to see that there are two ways for integration:
Currently, the single plugin will be released first. Then MB AIO will be released later with a bundle of other extensions. So you can see the MB Elementor Integrator in MB AIO is an older version 2.1.7.
If you want to use the new version, you can install and activate the single plugin, it will override the functionality of the plugin in MB AIO.
