Hello all, 

we have an urgent problem on a production site of DNN 5.4 !

After the automatic installation of this security update for IIS 7

Cumulative Security Update for Internet Explorer 7 for Windows Server 2008 (KB2809289)

We have the following Error that blocks DNN: 

System.ArgumentException: The string parameter 'tagPrefix' cannot be null or empty. Parameter name: tagPrefix at System.Web.UI.TagPrefixAttribute..ctor(String namespaceName, String tagPrefix) at System.Reflection.CustomAttribute._CreateCaObject(RuntimeModule pModule, IRuntimeMethodInfo pCtor, Byte** ppBlob, Byte* pEndBlob, Int32* pcNamedArgs) at System.Reflection.CustomAttribute.CreateCaObject(RuntimeModule module, IRuntimeMethodInfo ctor, IntPtr& blob, IntPtr blobEnd, Int32& namedArgs) at System.Reflection.CustomAttribute.GetCustomAttributes(RuntimeModule decoratedModule, Int32 decoratedMetadataToken, Int32 pcaCount, RuntimeType attributeFilterType, Boolean mustBeInheritable, IList derivedAttributes, Boolean isDecoratedTargetSecurityTransparent) at System.Reflection.CustomAttribute.GetCustomAttributes(RuntimeAssembly assembly, RuntimeType caType) at System.Reflection.RuntimeAssembly.GetCustomAttributes(Boolean inherit) at System.Web.UI.AssemblyCache.GetAjaxFrameworkAssemblyAttribute(Assembly assembly) at System.Web.UI.ScriptManager.get_DefaultAjaxFrameworkAssembly() at System.Web.UI.ScriptManager..ctor() at DotNetNuke.Framework.AJAX.AddScriptManager(Page objPage) 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)

Thanks a lot for any help to get this fixed as fast as possible !

Best regards, 
Fabianus

there was a known issue with the gallery module and particular IIS configuarations (http://www.dotnetnuke.com/Resources/F...) - if you are using it you may want to upgrade (also, I highly recommend upgrading to a more recent version of dotnetnuke)
