When upgrading my site to PHP8+ I get the following error:
foreach() argument must be of type array|object, int given
location:
wp-content/plugins/meta-box-aio/vendor/meta-box/meta-box-columns/src/Processor.php:73
MetaBox\C\Processor->parse_columns()
wp-content/plugins/meta-box-aio/vendor/meta-box/meta-box-columns/src/Processor.php:40
MetaBox\C\Processor->__construct()
wp-content/plugins/meta-box-aio/vendor/meta-box/meta-box-columns/meta-box-columns.php:30
mb_columns_add_markup()
wp-includes/class-wp-hook.php:307
apply_filters('rwmb_meta_box_settings')
What needs to be done to resolve this?
.
