Just moved a site from IIS6 to IIS7.5 (w2K8 server R2) and wnated to be able to debug a bunch of old Classic ASP sites. I followed the instructions to disable the friendly messages, but these settings have no effect.
I still always get (Internal Server Error... ) friendly messages.
I've restarted the website, the webserver, to no avail.
I've cleared caches, histories, etc on both FF36 and IE8, but it looks like a bug in IIS7.5
