Yesterday we installed SDL Web 8.5 and try to login CME. I got error.

/WebUI/Core/Services/Communicator.svc/Invoke failed to execute. STATUS (404): Not Found

Any one have idea how to resolve this issue.

  • I think we will need (much) more info than this. I also installed 8.5 this morning, and I don't get this error. - Was it an upgrade? Any errors logged in the Windows Event logs? Have you tried turning on Tracing? Any errors logged in the browser console? – Nuno Linhares Dec 22 '16 at 19:09
  • Yes Nuno, it`s upgrade sdl web 8.1 to sdl web 8.5 – Sudhakar Rao Dec 22 '16 at 19:11

We just had a similar case after installation of 8.5 - all svc services were returning 404. It turned out that there were no Handler Mappings in IIS for *.svc so we had to add "HTTP Activation" for .NET Framework 4.6 WCF Services (Server Manager > Add Roles and Features > Features).

HTTP Activation

  • wcf activation enabled? – Sudhakar Rao Oct 3 '17 at 14:15
  • @SudhakarRao Please see the screenshot I added to the answer. This is on Windows Server 2016. – lajavko Oct 4 '17 at 15:23
