I Just recently installed DNN 8.0.0.0 and it is perfect.

I installed the latest stable version of DNN Blog but I faced this problem when I tried to add a new blog. 

The Manage.ascx failed to load: 

Error: is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: Unknown server tag 'dnn:DNNGrid'. ---> System.Web.HttpParseException: Unknown server tag 'dnn:DNNGrid'. ---> System.Web.HttpParseException: Unknown server tag 'dnn:DNNGrid'. ---> System.Web.HttpException: Unknown server tag 'dnn:DNNGrid'. at System.Web.UI.TagPrefixTagNameToTypeMapper.System.Web.UI.ITagNameToTypeMapper.GetControlType(String tagName, IDictionary attribs) at System.Web.UI.MainTagNameToTypeMapper.GetControlType2(String tagName, IDictionary attribs, Boolean fAllowHtmlTags) at System.Web.UI.MainTagNameToTypeMapper.GetControlType(String tagName, IDictionary attribs, Boolean fAllowHtmlTags) at System.Web.UI.RootBuilder.GetChildControlType(String tagName, IDictionary attribs) at System.Web.UI.ControlBuilder.CreateChildBuilder(String filter, String tagName, IDictionary attribs, TemplateParser parser, ControlBuilder parentBuilder, String id, Int32 line, VirtualPath virtualPath, Type& childType, Boolean defaultProperty) at System.Web.UI.TemplateParser.ProcessBeginTag(Match match, String inputText) at System.Web.UI.TemplateParser.ParseStringInternal(String text, Encoding fileEncoding) --- End of inner exception stack trace --- at System.Web.UI.TemplateParser.ProcessException(Exception ex) at System.Web.UI.TemplateParser.ParseStringInternal(String text, Encoding fileEncoding) at System.Web.UI.TemplateParser.ParseString(String text, VirtualPath virtualPath, Encoding fileEncoding) --- End of inner exception stack trace --- at System.Web.UI.TemplateParser.ParseString(String text, VirtualPath virtualPath, Encoding fileEncoding) at System.Web.UI.TemplateParser.ParseFile(String physicalPath, VirtualPath virtualPath) at System.Web.UI.TemplateParser.ParseInternal() at System.Web.UI.TemplateParser.Parse() at System.Web.Compilation.BaseTemplateBuildProvider.get_CodeCompilerType() at System.Web.Compilation.BuildProvider.GetCompilerTypeFromBuildProvider(BuildProvider buildProvider) at System.Web.Compilation.BuildProvidersCompiler.ProcessBuildProviders() 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, 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.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at System.Web.UI.TemplateControl.LoadControl(String virtualPath) at DotNetNuke.UI.ControlUtilities.LoadControl[T](TemplateControl containerControl, String ControlSrc) at DotNetNuke.UI.Modules.WebFormsModuleControlFactory.CreateControl(TemplateControl containerControl, String controlKey, String controlSrc) at DotNetNuke.UI.Modules.WebFormsModuleControlFactory.CreateModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleControlFactory.LoadModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleHost.LoadModuleControl() --- End of inner exception stack trace ---

I believe that is related to the Telerik controls being moved to a different DLL, it likely means that the DNNBlog module needs a recompile to fix. Just to be sure, you grabbed the latest (12/15/2015) release from GitHub?

Thanks for mentioning this change of DNN 8. However, I'm facing this problem in BLOG version 06.02.02 which the most latest one. 

I think we need to wait them to recompile the DNN BLOG and release another version.

I downloaded the source and tried that but could recompile it.

Any suggestions !

I got exactly the same problem.

Installed DNN 8.0.0 which went fine. Then installed Blog_06.02.02_Install and the installation went fine, but when I try to open "Manage" I get exactly the same error message. Any hints on workarounds? I don't want to go back to an earlier version of DNN, but would it help to use an older version of the blog module?

What Chris Hammond said is the right answer, you just need to recompile the source again using the new dotnetnuke libraries.

I did that and it worked.

you have to do the following :

1- download the source of latest version of the blog from github.

2- open it using VS and remove the old reference for Dotnetnuke.dll , Dotnetnuke.Web (that actually used to have the dnn telerik wrappers controlls)

3- add the new library that contains the deprecated dnn wrappers controls for telerik which is (Dotnetnuke.Web.Deprecated.dll) of course you can get it from the DNN 8 bin folder.

4- now you need to go to Manage.ascx file and comment out the register directives for the following namespaces :

<%--<%@ Register TagPrefix="dnn" Namespace="DotNetNuke.UI.WebControls" Assembly="DotNetNuke" %>--%>

<%--<%@ Register TagPrefix="dnn" Assembly="DotNetNuke.Web" Namespace="DotNetNuke.Web.UI.WebControls" %>--%>

5- you have to register the new directive for dnn telerik controls that is in Deprecated dll you just added to reference in step 3

<%@ Register TagPrefix="dnn" Namespace="DotNetNuke.Web.UI.WebControls" Assembly="DotNetNuke.Web.Deprecated" %>

Kindly note that you have to do step 5 in any other *.ascx file that use dnn telerik controls .

 

6- final step rebuild the solution and you will get error because you have to update another reference for  " System.Web.Http.dll" because the DNN 8 use the new one that Blog source does have the old. so Just remove the reference and added new "System.Web.Http.dll" from the DNN 8 bin folder.

7- Build again and hopefully it works.

8- go to the obj/release folder in the solution and you will see the "DotNetNuke.Modules.Blog.dll" complied  just copy it to your DNN 8 bin folder and of course you will asked to replace the it with already old existed one.

9- replace the Manage.ascx file as well in Desktop Modules folder in your DNN8.  and any other changed *.ascx files. 

 

10- Enjoy , and please tell me in case anything happened ! :)
