SharePoint 2013 Troubleshooting - "Unable to create the folder in SharePoint Document Library"
Recently I received the error message “Unable to create the folder in SharePoint Portal” when try to create a folder in document library in a SharePoint 2013 site which setup by others. I found out below error message in “Windows Application Log” Event viewer when every time fails to create a folder: WebHost failed to process a request. Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/62723292 Exception: System.ServiceModel.ServiceActivationException: The service '/_vti_bin/client.svc' cannot be activated due to an exception during compilation. The exception message is: A binding instance has already been associated to listen URI 'http://xxxxx/_vti_bin/client.svc'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config. . ---> S
