How to access Apple Support Communities? Stuck at Manage Apple ID-page, keeping redirected to it

If not logged in, I can see the Forum.

If logged in, I cannot see the Forum, links to it redirect to https://appleid.apple.com/account/manage

The page that looks like this instead of the forum all the time:

That's possible.

I remember also once had to make an iCloud.com-address.

It's linked to my Apple ID (@mac-com)-address.

I used it trying to login at this Forum.

I got the same page (Manage your Account).

I can't edit, it says:

APPLE ID

Yes – it's the account I use for everything still today. I can't change it to something else.

This is my own screen:

I cannot get past this screen to Apple Discussions / Communities, only with another account which I use now (iOS5User). This is not my own account, but from my aunt and linked to her e-mail, Apple ID, etcetera.

So Yes I can login, No I can't acces Apple Support Communities Forum. Because if I try, I keep begin redirected to my Manage Your Apple ID-screen (pictured above).

Also strange but interesting is..., I just found out, while logged in with this user (iOS5User, my aunts Apple-account), i'm still able to login at https://appleid.apple.com/ with my own r.......@mac.com-account at the same time! However, Communities is still logged in as iOS5User, my aunts Apple-account.

I think this is really strange and maybe I have to have an Apple employer asked to look at it. I don't know if that is possible via this thread? (I have no Chat option here in The Netherlands).

Anyway thanks for your time, if you know other options then I would like to know them.

And if it's solved anyhow, I'll surely will post it here!

Thank you!

I'm only using one browser, Safari. I don't know if I can post my account name here for security reasons?

I received an e-mail from Apple Support, and will reply if I get an answer/solution! Thank you for your time and support!

I will post here if the problems are solved!

Unfortunately, I can't remember if I ever was able to log in to Apple Discussions with my own (old) @mac.com account. I can't find my user name (before @mac.com) with search, so maybe not.
