The custom cms is not working. When we try to use it, we get a generic error page from host. The site worked fine since 2011. Now all of a sudden it does not. I contacted host and they said they have not upgraded any iis or anything like that. Host said I am to upload a web.config file to the root so that the host can see a more detailed file on where the problem could be. I don't know what a web.config file is. I asked host if I could go to the web and grab one of the generic web.config files. She said she would not do it that way. She recommended that I contact the programmer which we haven't used since 2011 and ask him to create a web.config file. Why can't I just use a generic? I am not familair with asp so I am kinda at a loss.
What is the error message your are getting?
Web.config is only for IIS served websites
