Using DNN: 04.05.01
Forum: 04.04.03
Forum is Normal, Public, Moderated.

These issues all happened after upgrading from the previous version.

1. I have the forum module installed on a page. When I try and uncheck the edit box for 
the all users group on the page, and save the page, the edit module box still shows as 
being checked.

2. When I go into the forum module settings, and look at the permissions for the all users group for:

Edit Module
Forum Admin
Global Moderator

These are still showing as being checked. When I uncheck and click on update, they still 
show as being checked and I'm not able to change this.

Note that inherit view permissions is not checked.

3. When I go into manage forum users, it is showing everyone in the DNN community in the 
user list, even though there is a much smaller number of forum users in the acual database
table for users.

Is this the default behavior now?

4. When I click on a user, the email moderator checkbox is always checked. When I uncheck 
it and save, it still shows as checked.

5. When I go into managing users, it always shows that the user is trusted.

The box is grayed out and I am not able to change it.

I've spent hours on these trying to resolve, but have not been able to find a solution.

Would appreciate any suggestions anyone might have on this.

1. Yes, Module settings. This was not the case using the older forum. This is the behavior since updating.

What do you mean by core communication issue, and where would I go to fix it?

2. Same as 1.

3. OK, understand, this makes sense then.

5. I went to Admin -> general setting and disabled the Lock User Trust checkbox. (Unchecked it.)

I then saved the settings, and it correctly showed the unchecked Lock user Trust checkbox.

When I go back into a user record, the trused user is still checked and checkbox is not accessible.

Using an administrator login, I changed this as you're saying, went into a user record, and the box was still greyed out and still could not change. Forum is public, moderated.
