I recently upgraded my IE to version 10 for Win7. Since then, I was not able to access my project centre. I kept getting this error message.
After racking my brains for a while, I tried setting the compatibility mode for this PWA site. Note: You can do this via IE Tools.
This worked a treat!! I was able to access by project centre again.
There you have it. Hope this made your day!!
