Activating Meta Box AIO crashes my website. I've isolated the plugin conflict to GT3 ListingEasy Core Plugin, but the debug error is coming from Meta Box AIO. The error message is below.
Fatal error: Uncaught Error: Call to undefined function MBB\Upgrade\rwmb_request() in /home/318100.cloudwaysapps.com/ugjrfarvat/public_html/wp-content/plugins/meta-box-aio/vendor/meta-box/meta-box-builder/src/Upgrade/Manager.php:15
