Hi

I'm new to dnn. Today I download forum module version 4.4.3 and try to update it to the current one. The result page shows that everything is installed sucessfully but when I try to add module to a page, the error message is show as below

Error: Forum is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: D:\DNN\DesktopModules\Forum\Forum_Container.ascx(3): error BC30451: Name 'ForumConfig' is not declared. ---> System.Web.HttpCompileException: D:\DNN\DesktopModules\Forum\Forum_Container.ascx(3): error BC30451: Name 'ForumConfig' is not declared. at System.Web.Compilation.AssemblyBuilder.Compile() at System.Web.Compilation.BuildProvidersCompiler.PerformBuild() at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at System.Web.UI.TemplateControl.LoadControl(String virtualPath) at DotNetNuke.UI.Skins.Skin.InjectModule(Control objPane, ModuleInfo objModule, PortalSettings PortalSettings) --- End of inner exception stack trace ---

I don't know why it's happen. Does anyone has an idea or advice for this problem?
Thank you in advacnce
