Fix this Notice, we just do this : create a VM Menu and assign it to a module.
steps are :
1/. in "MenusMenu Manager" choose "add New Menu" (i type : VM Fix Menu for example)
2/. you will see "Menu successfully saved",
after that find this notice "add a module for this menutype", click on this to create the module for it
3/. in "MenusMenu Manager" choose VM Fix Menu menu , then create a menu in this
we have done !!! the Notice will disappear when we have done step 3. !!! Good Luck and have fun !!!
