How do you test webdirect? Can you post a screenshot of your browser's address bar?
And from your admin console status page showing the bottom half with the web engines?
To test WebDirect, you can use the following URL on the localhost, http://localhost/fmi/webd. This will show you the WebDirect home page and show you a link for the example database.
It turned out that there had been an issue getting the web publishing engine to work during my install.
All of the IIS configuration was correct and all of the required folders had been created, but WebDirect would not activate in my FMS server and there was no info for it on my server’s status page.
Rather than trying to troubleshoot, I decided to uninstall FMS15, restart the server and re-install FMS15.
This time everything fell into place correctly and I could see the WebDirect status info and the test link worked.
Don’t know what happened the first time, but I got there in the end.
