However, I have some very frustrating problems. I was trying to solve them for a couple of hours now (tried to find out what can cause this error by inspecting the SRC script version) but without any success.

Installation procedure went without any problems, I am able to use forum as an administrator and as a user (write post and basically everything) but I am not able to manage the website using Admin and Host links.

I get the following errors (I thought that it is easier to see the problems on the screenshot, rather than copy-paste the code):

This is my Web.config:

As you can see it is slightly modified (removed db.config and put connections string inside etc.).

What is important: I handled my page authentication without any membership providers. But I was forced to write MembershipProvider and RoleProvider in order to integrate YAF (I used YAF ProfileProvider). But those (my) providers are just "empty" and implement only needed functions by YAF e.g. GetUser (registration via YAF would be disabled).

Here are sensitive parts of those two providers (I hope those would be helpful to solve my issue):

And thanks in advance for any help!! (and your time) Basically thanks for any words!!

Please, take a look on it. Thanks.
