Cannot create an instance
Hi, we have just had this error message, which we are unsure why it happened. The only way we could fix it was to upload the web.config file to reboot the system. Sitefinity is working again but we would like to know why this may have happened. All we did was add a user to the backend.
Thanks,
O.
