Hi Dexter

What kind of setup do you have? Sounds weird to me that wordpress is not able to run due to some .dll files it can't see since wordpress is based on PHP?

Looking forward to hearing a bit more details.

My root web has all the Umbraco files under it.  These files and folders do have the required access for the asp.net 4.0 user.  I have created a virtual directory (/blog) for Wordpress in the Umbraco web which points to a folder outsite the Umbraco folder that holds all the Wordpress files.

Before I upgraded to Umbraco 4.11.1, I was running Umbraco 4.9.0 and everything ran smoothly.  It just seems really odd, that the files that says are missing, are in the bin folder.

I have commentted out <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> from the web.config, then it says it cannot load System.Web.Mvc.  I commented out <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />, then it says it cant load <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />.  When I comment out that, I get error saying 'System.IO.FileNotFoundException: Could not load file or assembly 'UrlRewritingNet.UrlRewriter' or one of its dependencies. The system cannot find the file specified.'

From what I understand, these .dll are needed for ASP.net MVC.  I do not have the ASP.net MVC installed on this box, so I am cluesless as to why this is happening.

Is it a requirement that I have to upgrade to 4.10 first?

Another thing.  I had to get a hotfix for the v4.9.0 installation.  the original v4.9.0 umbraco.dll had a problem with URL's with a ~.  The patched file given to me was issued in inlinexsltfix490.zip (umbraco.dll  9/24/2012 8:47 AM file version 1.0.4640.26027)

I have also attempted to take baby steps and upgrade from 4.9.0 to 4.10.1.  The main site comes up correctly, however when I attempt to open the wordpress site I get the same error:

Server Error in '/blog' Application.
