Since last four days I am struggling with ver 5.03.01 of dotnetnuke. I have no previous experience with dotnetnuke. It is not letting me add a page to the site and giving the following error. However I was able to add pages using ver 4 of dotnetnuke.
Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: C:\inetpub\wwwroot\DotNetNuke_Community_05.03.01_Install\DesktopModules\Admin\Tabs\ManageTabs.ascx.vb(243): error BC30456: 'OutputCachingProvider' is not a member of 'System.Web.Caching.OutputCache'. ---> System.Web.HttpCompileException: C:\inetpub\wwwroot\DotNetNuke_Community_05.03.01_Install\DesktopModules\Admin\Tabs\ManageTabs.ascx.vb(243): error BC30456: 'OutputCachingProvider' is not a member of 'System.Web.Caching.OutputCache'. at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResult(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean ensureIsUpToDate) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at DotNetNuke.UI.ControlUtilities.LoadControl[T](TemplateControl containerControl, String ControlSrc) at DotNetNuke.UI.Modules.ModuleHost.LoadModuleControl() --- End of inner exception stack trace ---
Anybody help? There is no related solution for this problem on this forum or net. Maybe I am making some basic mistake, I would appreciate if any leads are provided..
