Hi!
It seems your great plugin (v1.9.1 installed), has some incompatibility with another plugin I love: polylang (https://wordpress.org/plugins/polylang/) installed version: v1.6.
The simptoms are:
1.- Foodlist Settings page yells two warnings:
Warning: Missing argument 2 for PLL_Plugins_Compat::cft_copy() in C:\xampp\htdocs\montbell\wp-content\plugins\polylang\include\plugins-compat.php on line 129
Warning: Missing argument 2 for PLL_Admin_Sync::add_meta_boxes() in C:\xampp\htdocs\montbell\wp-content\plugins\polylang\admin\admin-sync.php on line 48
(And the worst...)
2.- Menuitem tags doesn't works: on menuitem creation or edition, it is not possible to add a tag, as it returns 'No matches found' and doesn't let me assign any.
And what's more: any previously assigned tag (while polylang is deactivated) disappears on polylang activation.
Let me know if I can help you in any way.
Thanks in advance!
