Conflict with plugin If-Menu

We’re using a plugin called If-Menu:

https://ww.wp.xz.cn/plugins/if-menu/

Unfortunately, there are some conflicts with your Nested-Pages plugin.

The issue is the “Sync Menu” option at the top of the Page Manager. When checking this option, the following warning is thrown from the If-Menu plugin:

PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/if-menu/if-menu.php on line 223

The line in question of that plugin is:

foreach ( $_POST['menu-item-if-menu-enable'][$menu_item_db_id] as $index => $value ) {

Apparently the $_POST[‘menu-item-if-menu-enable’][$menu_item_db_id] array for the If-Menu plugin isn’t being set properly when checking the Sync Menu option of your Nested Pages plugin.

I would like to fix this issue and would appreciate a point in the right direction.

And thank you for an awesome plugin. Really makes managing pages in the admin easier than the current default WP page management system.
