[solved] New left side bar menu

Hi, I can see that I have too many questions.Sorry but please understand that Opigno is so Good that I can not spent my time away from it.On the left sidebar menu where there "Home", My Courses" " Forum"...., I want to create a new which I will call "Outils" to display a calculator and dictionaries.To create the menu " Outils", I use Structure ---> Menu ---> Main Menu.First step for me is the calculator.I build a module calculator.When I load the module and clik on the Menu "Outils", I have " Page not found".I put the module and the screen short on the link : http://www.enligne-ci.net/FYLES/ Is there anything, I am doing wrong ? Thanks

Hi adon,

Hi adon, You probably have not defined correctly the menu hook in your module https://api.drupal.org/api/drupal/modules%21system%21system.api.php/function/hook_menu/7 Best regards
