Dear Adequation Team,

I am using your extension on my site. It seems ok when I set the language to English in the internet option of my browser. But when I set to Chinese, the following error occurs:

DotNetNuke.Services.Exceptions.PageLoadException: Culture name 'zh' is not supported. Parameter name: name ---> System.ArgumentException: Culture name 'zh' is not supported. Parameter name: name at System.Globalization.CultureTableRecord..ctor(String cultureName, Boolean useUserOverride) at System.Globalization.CultureTableRecord.GetCultureTableRecord(String name, Boolean useUserOverride) at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride) at System.Globalization.CultureInfo..ctor(String name) at Adequation.DNN.LocalizationExtensions.LE.GetValidLanguageCode(Int32 portalId, String culture) at Adequation.DNN.LocalizationExtensions.CssMenu.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.AddedControl(Control control, Int32 index) at System.Web.UI.ControlCollection.Add(Control child) at DotNetNuke.Framework.DefaultPage.Page_Init(Object sender, EventArgs e) at System.Web.UI.Control.OnInit(EventArgs e) at System.Web.UI.Page.OnInit(EventArgs e) at DotNetNuke.Framework.PageBase.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

what's the problem?

There are also another problem:  When I log in as admin, the admin and host menu disppears! It seems all the menu on the same level with root language page disppeared.  My skin uses cssMenu from skinnet which is supported according to your documentation. My DNN version is 5.1 and my site is www.joylittle.com. if you need I can also provide an admin account for your investigation. thanks and best regards
