[BUG] Statistics not showing

Hi, there is a problem in the “visitor” view : the plugin does not show the list of OS and number of visitors. There is an error in the page code that may be due to the use of french letter “è” in a variable name. Here is the console :

Uncaught Error: Syntax error, unrecognized expression: #vistor_panel_Système d’exploitation at I.error (load-scripts.php?c=1…t&ver=7.0.4:2:11769) at Y (load-scripts.php?c=1…t&ver=7.0.4:2:17234) at re (load-scripts.php?c=1…t&ver=7.0.4:2:20008) at ce.I (load-scripts.php?c=1…st&ver=7.0.4:2:7520) at ce.<anonymous> (load-scripts.php?c=1…st&ver=7.0.4:5:2898) at e.<computed> [as find] (load-scripts.php?c=1…st&ver=7.0.4:5:1582) at ce.fn.init.find (load-scripts.php?c=1…t&ver=7.0.4:2:21991) at ce.fn.init (load-scripts.php?c=1…t&ver=7.0.4:2:22483) at e.<computed>.<anonymous> (load-scripts.php?c=1…st&ver=7.0.4:5:2438) at new e.<computed> (load-scripts.php?c=1…st&ver=7.0.4:5:1582)
