IISManager won't load after modifying applicationHost.config

IISManager won't load after modifying applicationHost.config. I replaced

<section name="httpErrors" overrideModeDefault="Allow" />`

with

<httpErrors errorMode="Custom"> <clear/> <error statusCode="404" path="404.html" responseMode="ExecuteURL"/> </httpErrors>

It didn't work and then IISManager wouldn't load anymore. I go to https://.scm.azurewebsites.net/IISManager/ and get a 404 error. I've tried to uninstall the extension and reinstall many time but it doesn't work. I need to fix the applicationHost.config but can't now because the extension won't load.

Delete the applicationHost.xdt existing in "D:\home\site" using Kudu or FTP.

I did that. It doesn't fix it.

Umm. Were you restarting Web App and did not recover?

Happened for me once too, but it fixed itself after about half a minute. No idea what that was.
