This is merely a guess by looking at the stack trace but if MVC 2 installed on the machine?
Yes it is. To make a bit more strange: I already have about 8 sites on the same servers running CMS6R2. What i suspect now is thats something is wrong in this sites web.config, but i cannot figure out what that would be...
Correction: The site stops working when the upgrade from 5R2 -> 6 is done, and remains after upgrading to 6R2.
As Linus suspected it did have to do with MVC. Thanks for the tip!
The solution can be found in my blog: http://world.episerver.com/Blogs/Jonas-Lindau/Dates/2013/4/The-annoying-error-CS1031-Type-expected-after-upgrade-site-from-CMS5R2-to-CMS6/
I have seen a lot of strange errors during upgrades but this one was new. The site is upgraded from CMS5R2 -> 6 -> 6R2. When accessing the dashboard/edit/admin the loginbox appears, but efter login i get this error. Any ideas?
