Hello,
I recently deployed my site and the following problem occurred:
Module ProtocolSupportModule
Notification SendResponse
Handler ExtensionlessUrlHandler-Integrated-4.0
Error Code 0x80070021
Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
Config File \\?\E:\Domains\oliveiramercadoonline.com.br\wwwroot\web.config
69: <system.webServer>
70: <httpProtocol>
71: <customHeaders>
Before this problem, I had to comment this line "<urlCompression doStaticCompression="true" doDynamicCompression="true" />" because it was giving another error
