Hello there,

finally i got it to install DNN :)
i played a little with my protal and closed my Browser by Mistake.

i tryed to login again but got the following Error:

A critical error has occurred.
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.


so what should i do now ? ?

thx for your help - yes it was the cache :) best regards - tom
