Cannot use control panel of our website

we can just login to control panel but error for all feature we can not do any things..

Hi Amer,

Can you please open developer console in google chrome and then refresh the page. Then find 404 request in Networks tab and send us info. It will give us more details to debug

like this?

I guess you are using IIS as web server for your application. Can you please confirm that you installed all modules and features for IIS correctly (documentation is here:  docs.sitefinity.com/configure-the-iis-to-host-sitefinity-projects)

Maybe HTTP Activation or something similar, which is needed for WCF services was not installed. And IIS is returning 404 error, when someone is trying to call *.svc

same error after follow steps..

Did you restart IIS after this steps?

And can you please execute this command in powershell (It will print all installed roles and features in your server)

And send me the result

can't update our website since 6 months bad satisfaction..

What i can suggest, is to ask Telerik Support to check what's wrong with IIS server. For some reason IIS is not processing *.svc requests.
