Yes! As you can see it is a very strange problem.

Don’t the full logs indicate any oddities that could be fixed?

I use this code in mu-plugins:

function lscwp_suppress_purge_update( $new_status, $old_status, $post ) {
    // Debug log: indicate function entry
    error_log( "[LSCache Debug] lscwp_suppress_purge_update called for post #{$post->ID}, type {$post->post_type}, status {$old_status}→{$new_status}" );

	if ( $post->post_type != 'flamingo_inbound' && $post->post_type != 'flamingo_contact' ) {
        // Debug log: post type not excluded
        error_log( "[LSCache Debug] Post type {$post->post_type} not excluded, exiting." );
		return;
	}

    // Debug log: post type is excluded
    error_log( "[LSCache Debug] Post type {$post->post_type} is excluded, starting ob_start()." );

	ob_start( function($buffer) use ($post) {
        // Debug log: inside buffer callback
        error_log( "[LSCache Debug] Inside ob_start callback for post #{$post->ID}, sending override header." );
		@header("X-LiteSpeed-Purge: nothing");
		return $buffer;
	} );

}
add_action( 'transition_post_status', 'lscwp_suppress_purge_update', 10, 3 );

should block purge-all triggered by form submission because Flamingo plugin saves flamingo_inbound and flamingo_contact records in _posts. Purge-all still triggers on every submission.

Here are all the logs capturing the last send:

I don’t understand what I should do, I’m on a shared server, not on a server with full access.

From the published debugs, what do you see, that it’s OK, but the purge-all still happens? I need a solution, is it possible that the script can’t be improved?

So… the code works on a staging site with Twenty Twenty-Five theme, but it doesn’t work with Divi theme. Maybe there is some problem intercepting the submissions because Divi uses a lot of Ajax?

I need to clarify something… I don’t need to prevent the purge of the post_type flamingo_inbound and flamingo_contact when a form is submitted.

I need to prevent the entire site from auto-purge when a form is submitted and Flamingo writes the post_type flamingo_inbound and flamingo_contact to the DB.

I’m not very good at coding, the line

if ( $post->post_type != 'flamingo_inbound' ) {
how would it be adding flamingo_contact too?
