Hi,

I have upgraded Umbraco from v7.3.8 to v7.7.7 and now I am getting a YSOD everytime I try to open a media file:

Any idea why is this happening?

In my web.config I have:

<remove assembly="System.Web.Http" />
    <remove assembly="System.Net.Http" />
    <add assembly="System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <add assembly="System.Web.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    <add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

and

<dependentAssembly>
    <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
  </dependentAssembly>

Thank you in advance.
