Hi Makar -Oracle,
From the screenshot, it appears that at the time it was captured, the user display name was still showing as the randomly-generated set of numbers and letters. This would indicate to me that the user account was not "fully baked" (i.e., synched to all systems) when the content search was made and the link clicked. This would prevent access to any of the gated areas of the community.
Be sure that you fully LOG IN to the community at https://community.oracle.com/welcome using your Oracle login credentials. (New users: Now is a good time to Update Your Community Display Name and Avatar!)
Fully LOG OUT of the community by choosing the LOG OUT option from your display name LOV.
Log back in to trigger a synch of any changes to all systems. You should now be all set.
If you still have problems after performing the above steps, reach out to the MOSC team at email@example.com, or create a non-technical SR in My Oracle Support.

I am a contractor so am not embedded in an organisation. I set up my own access, but now that I need to find stuff out, I can't get at it. How do I fix this?
When you say you set up your own access, does that mean you have paid for customer support from Oracle?
If you've paid, then you should have a CSI (Customer Support Identifier) and instructions for maintaining users within your "organisation" even if that's just yourself. Accounts with a CSI attached, should have access to both the public groundbreakers community (this community - open to everyone anyway) as well as the MOS (My Oracle Support) Community and support ticket site. Without an associated CSI, you won't have access to MOS or it's community.
There are also some places in the community (public and MOS) that are "internal" to oracle, so only accessible to oracle employees, or to those of us who are moderators. You won't be able to access those areas.
MOS, as already mentioned requires a premium. Other communities are free. You need to tell us what information you're are trying to access.
