Unable to communicate back with site to check for fatal errors

No error is showing, just the code is not working. Check the screenshot:

https://prnt.sc/sN2CGYqUF4on

Can you make sure the code is indeed activated?

Have you tried clearing the plugin first?

Let me know :)

I don't know what do you mean by clearing the plugin first. Can you please explain it for me?

Also, for your better understanding I have given the details in the private information.

I always clear the cache after something on my site. And, I am using Ezoic cache options for that! check the screenshot below

I request you to give the proper solution to solve this issue as soon as possible. I have given all my information in the above. If you need anything else, I can provide you. Make sure that my problem is solved !

Please refrain from making unreasonable demands, we are trying to assist you with adding custom code to your site. This is not our issue, and we are only trying to assist.

Can you first provide a link to a page on your website where we can see the date that you want to change?

I am not using any caching plugin. Also, there is no error message showing.

The fact is after adding the code on snippets plugins, it's not working.

I want to show my post last updated date on article, I tried with the code snippet but its not working.

HELP!!!

https://prnt.sc/aMCUiOOU4l3a this is not the GP function, and the function doesn't look right.

Can you use this snippet instead?

add_filter( 'generate_post_date_output', function( $output, $time_string ) {
$time_string = '<time class="entry-date published" datetime="%1$s" itemprop="datePublished">Published on: %2$s</time>';

if ( get_the_date() !== get_the_modified_date() ) {
$time_string = '<time class="entry-date updated-date" datetime="%3$s" itemprop="dateModified">Last Updated on: %4$s</time>';
}

$time_string = sprintf( $time_string,
esc_attr( get_the_date( "c" ) ),
esc_html( get_the_date() ),
esc_attr( get_the_modified_date( "c" ) ),
esc_html( get_the_modified_date() )
);

return sprintf( '<span class="posted-on">%s</span> ',
$time_string
);
}, 10, 2 );

And can you link us to a post that has an updated date?

Thanks Finally updated date is showing, GOD BLESS YOU ~

Glad to hear that :)
