I create a custom field “Post Object” like “post_parent”.
The amount of the post type is approximately 5000, then the UI is broken.
> Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 72 bytes) in /path/to/wordpress/wp-includes/meta.php on line 826
I just want to set other post ID to custom field.
Can I limit to showing the select box UI to avoid memory exhausting?
I changed the ACF type from “Post Object” to “Integer”.
Then I cannot select “Post Object” from select box at admin panel, but my Program can control the value with relation.
