Hi,

I am experiencing this issue whenever I right click on a page and select "Properties".

We are running DW 9.4.34 but somehow its looking for 9.0.0.0?

Server Error in '/' Application.

Hi Martin,

The reason it says version 9.0.0.0 is because it's using the assembly version, not the informational version. The Dynamicweb assemblies are versioned with an assembly version separate from the actual version of Dynamicweb. For Dynamicweb.dll and Dynamicweb.Admin.dll, they are versioned according the the major software version, in this case "9" but they have informational versions (product version if you use File Explorer to inspect it) of the actual version of the assembly, e.g. 9.4.34. You can read about versioning here: https://docs.microsoft.com/en-us/dotnet/framework/app-domains/assembly-versioning#version-information. Be aware that this may change with future major versions of Dynamicweb.

Now, for your actual issue. I think you have a mismatch between you Admin folder and your bin folder. I would recommend downloading the latest version of 9.4, which is 9.4.20, from the Doc-site and make sure you use the Admin and bin folder contained in that package.
