Drag and Drop on Menu (JS bug)

Hi,

I’ve installed your plugin, with WP, on my local machine (MAMP) and it works well for configuring the admin menu for different roles (and it’s cool !).

Now, when I install, on a server, the same version of WordPress (4.6.1), with the same (French) language activated, with the default theme, and only with your plugin : if I select the “Menu” settings, I can see a JS bug on the console :

wpNavMenu.menuList is undefined

And the Drag and Drop doesn’t work, menu items can’t be opened, etc…

If I look at the html source, i can see :

/* <![CDATA[ */
var userSettings = {“url”:”\/finale\/”,”uid”:”1″,”time”:”1480496887″,”secure”:””};
/* ]]> */

where, on my local machine, I have :

/* <![CDATA[ */
var userSettings = {“url”:”\/wordpress461\/”,”uid”:”1″,”time”:”1480495007″,”secure”:””};var wpAjax = {“noPerm”:”D\u00e9sol\u00e9, vous n\u2019avez pas l\u2019autorisation de faire cela.”,”broken”:”Une erreur non identifi\u00e9e est survenue.”};var postBoxL10n = {“postBoxEmptyString”:”Glissez les blocs ici”};var navMenuL10n = {“noResultsFound”:”Aucun r\u00e9sultat.”,”warnDeleteMenu”:”Vous \u00eates sur le point de supprimer d\u00e9finitivement ce menu.\n \u00ab Annuler \u00bb pour abandonner, \u00ab OK \u00bb pour le supprimer.”,”saveAlert”:”Les modifications que vous avez faites seront perdues si vous changez de page.”,”untitled”:”(Aucune information)”};
var menus = {“oneThemeLocationNoMenus”:””,”moveUp”:”Monter d\u2019un cran”,”moveDown”:”Descendre d\u2019un cran”,”moveToTop”:”D\u00e9placer tout en haut”,”moveUnder”:”Placer sous %s”,”moveOutFrom”:”Sortir de sous %s”,”under”:”Sous %s”,”outFrom”:”Sortir de sous %s”,”menuFocus”:”%1$s. \u00c9l\u00e9ment de menu %2$d sur %3$d.”,”subMenuFocus”:”%1$s. Sous-\u00e9l\u00e9ment num\u00e9ro %2$d sous %3$s.”};/* ]]> */

Have you an idea about what’s going wrong on the server ?
An authorization thing ?

Thanks by advance,
Denis
