error: the details of the application error from being viewed remotely
Dear olga is clear what the message says. Turn off the custom errors to see the details about this error for fix it, and then you close them back. So add mode="off" as:
<configuration> <system.web> <customErrors mode="Off"/> </system.web></configuration>Relative answer:Deploying website: 500 - Internal server error
By the way: The error message declare that the web.config is not the one you type it here. Maybe you have forget to upload your web.config ? And remember to close the debug flag on the web.config that you use for online pages.
This can be the message you receive even when custom errors is turned off in web.config file. It can mean you have run out of free space on the drive that hosts the application. Clean your log files if you have no other space to gain on the drive.
In my case I got this message because there's a special char (&) in my connectionstring, remove it then everything's good.
Cheers
