When trying to edit a custom Field Group I get the following error:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 4198400 bytes) in hidden/wp-includes/functions.php on line 3737 There has been a critical error on your website. Please check your site admin email inbox for instructions. Learn more about debugging in WordPress.
Do you have any idea what could be the issue? I can still edit Post Types.
