Hi guys

I’ve got a fix for the issue and if you have time, please replace the following function into the api-helpers.php file:

function acf_verify_nonce( $nonce, $post_id = 0 ) {
	
	// vars
	$r = false;
	
	
	// note: don't reset _acfnonce here, only when $r is set to true. This solves an issue caused by other save_post actions using this function with a different $nonce
	
	
	// check
	if( isset($_POST['_acfnonce']) ) {

		// verify nonce 'post|user|comment|term'
		if( is_string($_POST['_acfnonce']) && wp_verify_nonce($_POST['_acfnonce'], $nonce) ) {
			
			$r = true;
			
			
			// remove potential for inifinite loops
			$_POST['_acfnonce'] = false;
			
		
			// if we are currently saving a revision, allow its parent to bypass this validation
			if( $post_id && $parent = wp_is_post_revision($post_id) ) {
				
				// revision: set parent post_id
				$_POST['_acfnonce'] = $parent;
				
			}
			
		} elseif( $_POST['_acfnonce'] === $post_id ) {
			
			$r = true;
			
			// remove potential for inifinite loops
			$_POST['_acfnonce'] = false;
			
		}
		
	}
		
	
	// return
	return $r;
	
}

Please also let me know if this solves the issue for you

Thanks
