php foreach error on php7.1

Replies: 0

Hello,
the plugin seems to work fine, but I get the following error each time any page (even when the menu is not present) is accessed:

PHP message: PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/menu-image/menu-image.php on line 316

I am on WP 4.7.5 and php 7.1. No error on php 7.0.

Regards
