If this is a website you've visited there isn't much you can do to fix this as it is usually a problem their end and would require a .NET developer or IIS administrator to resolve.

If this is your website, you need to go to the server it's set it up on and read the error logs to find out what the configuration issue is. Chances are a reload of your files will take care of the error. You might need to contact the isp tech support to sort the issue.

If it isn't your website, there is nothing you can do. The error isn't on the browser side, it's something to do with the setup. either come back later or find another site to read. It isn't fixable on your end.
