critical error on your website Caused by Rank math

Hello @studyshoot

Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.

Assuming you are using the latest version of all the plugins, themes and WordPress (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.

To determine that, please follow this troubleshooting guide:

Only the site admin would know and your users won’t be affected by this troubleshooting.

Looking forward to helping you.

I have done this already and I have found the Problem which was with ACF + Custom post type..
I tried to Enable the Gutenberg Editor on the Custom post type ‘show_in_rest’ => true, and that works fine, returning to the Classic Editor which used by ACF Plugin is getting me back through the same Problem …
Thanks

Hello @studyshoot

How are you creating the Custom Post Types?

Looking forward to helping you. Thank you.

Thank you.

I am using the Custom post type using the WordPress register_post_type Functions;
I got this Error while updating a new Post using the a None Gutenberg Editor
/plugins/seo-by-rank-math/includes/replace-variables/class-base.php

also I got the Update Failed – Jason Error – while using the Gutenberg Editor …
The Problem is, it is happened while just updating old Posts and not create new posts

Thanks You.

Hello @studyshoot

Can you please share the register_post_type code so we can try to reproduce the issue on our setup?

The error you are getting is in the get_the_terms function of replacing variables. We had already added a condition there to check if the terms are empty.

Looking forward to helping you. Thank you.

function studyshoot_grants_post_type()
{
	$args = array( 
		'labels'=> array(
	'name'=>'Grants',
	'singular_name'=> 'Grant',
		),
		'hierarchical'=> false,
		 'show_in_rest' => true,
 		'public'=> true,
		'has_archive'=> true,
		'menu_icon'=>'dashicons-welcome-learn-more',
		'supports'=> array( 'title', 'author', 'thumbnail', 'editor' ),
		'slug' => '/grants',
		'rewrite' => true,
        'capability_type' => 'post',
	);
register_post_type('grants', $args);
}
add_action('init', 'studyshoot_grants_post_type');

Hello @studyshoot

Even after adding the code and creating a new Post in the Grants post type, we couldn’t reproduce the issue.

Can you please also run the conflict check?
