Icon Search Fails On Register Page

Hey @glark, not something I’ve run into before but I see what you mean.

It looks like it is a WP Ajax permissions issue. This plugin is only configured out of the box for authenticated calls to wp ajax.

A little proof of concept that would theoretically resolve this issue for you:

function ACF_FontAwesome_NoPriv_AJAX() {
	if ( class_exists( 'ACFFA_Loader_6' ) ) {
		$ACFFA_Loader_6 = new ACFFA_Loader_6();
		add_action( 'wp_ajax_nopriv_acf/fields/font-awesome/query', [ $ACFFA_Loader_6, 'select2_ajax_request' ] );
	}
}
add_action( 'acf/include_field_types', 'ACF_FontAwesome_NoPriv_AJAX', 20 );

This code would be added somewhere in your functions.php. Try it out and let me know if that works. I may add unauthenticated wp ajax calls for this function to a future update of this plugin but I need to think about it some more. I wouldn’t want something like that to become a vector for DDoS attacks or something.

Glad to hear it. No tip needed but I do appreciate the sentiment!
