We have an MVC ASP.net app on IIS 8.5, Win Server 2012 R2.
When we set web.config to:
<customErrors mode="Off" defaultRedirect="~/error" ></customErrors>
The site shows completely blank when there's an error.
Searching around I found that perhaps it might be because the app pool identity was set on site folder permission and indeed it wasn't, so I set it but that still did not fix it. It is set to Full Rights.
All other IIS settings for site are correct as far as I can tell, Windows Auth enabled, 32 bit site = True...
Anyone have any advice about what direction I could go next?
