DotNetNuke (dnn) - error on creating pages using version 5.6.3 - dotnetnuke

Question

I have installed DNN version 5.6.3 according to install instructions.
create new folder and copy downloaded content in
set permission for asp user and network service to full permissions on this folder
created a new db in sql server with a login for it as dbo
set the folder containing the site as an application in iis
amended the web.config file to have the correct db connection information in two places
Firstly I tried to install it with the typical settings but this never went any further than updating db (stayed on this for hours).
Therefore I installed it with the auto settings and this went through successfully as I can see.
Now on my new portal I can log in successfully and change my password on the host and admin user but I cannot do anything else, like creating new pages etc.
The error I am getting is this:

I had this (a previous version of dnn) installed on the same sever for a different client a couple years back and it worked fine, but I can't seem to make it work this time. I compared all the settings and nothing is different.
Has anyone got any experience with this version and an idea how I could progress?
From what I have found Googling, it sounds like it could be a permissioning problem on the server, but not sure where to start since I've given the NETWORKUSER full access to the directory already. Other suggestions seem to point towards .net 3.5 not being available to the website but I already have the framework installed.

Answer 1

Did you install the OpenID Authentication provider? You might need to delete that, or remove any reference to it from the web.config file.
You should also be sure, when you unzip the package for DNN, that Windows isn't blocking any of the files in the ZIP file. Right click on the ZIP file, and choose properties. If you see an "unblock" option do that, then extract the contents and try your installation again.
