I installed the dotnetnuke Blog module and am getting an error when I try to manage it:
Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Unknown server tag 'dnn:DNNGrid'.
---> System.Web.HttpParseException: Unknown server tag 'dnn:DNNGrid'.
I looked on their site but couldn't find much of anything.
You likely need to upgraded to the latest DNN8 specific release of the Blog module.
https://github.com/DNN-Connect/DNN-Blog/releases
https://github.com/DNN-Connect/DNN-Blog/releases/tag/06.03.00
DNN8 had breaking changes, that required some modules to be recompiled.
