If you get an HTTP 404 Error in a browser, after trying to access an IBM Connections Application and errors like
“File does not exist: E:/IBM/HTTPServer/htdocs/profiles”
start popping out in “error.log” file of the IBM HTTP Server, then most probably there is an issue with WAS Plugin.
I had this error just after the Installation of IBM Connections and the reason was the incorrect value of “WebSpherePluginConfig” variable, which contains the path to the “plugin-cfg.xml” file in the HTTP Server configuration. After the value was corrected and a correct path was supplied, IBM Connections could be accessed without any issue.
