Most likely causes:

* Managed handler is used; however, ASP.NET is not installed or is not installed completely.
* There is a typographical error in the configuration for the handler module list.

Things you can try:

* Install ASP.NET if you are using managed handler.
* Ensure that the handler module's name is specified correctly. Module names are case-sensitive and use the format modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule".

Links and More Information IIS core does not recognize the module.

Plesk creates application pools in Integrated mode and not other way. If you switch application pool to classic mode then you need to redefine the handlers directly in web.config. Otherwise you will get this error:
