 * I would like to use your plugin on a WP multisite install.
    Whether I use “network
   activate”, or I activate on a specific site, as soon as I activate, all my admin
   pages are displayed with the following error message, displayed 3 times : array_flip():
   Can only flip STRING and INTEGER values! in C:\inetpub\wordpressMUtests\wp-admin\
   includes\menu.php on line 274 Please notice I use a plugin developed by myself
   which customize how menus are displayed. But it works fine will all the other
   plugins I use. It is only when I activate your plugin that I get this error message.
   Please advise.
