[How can I access adult content? I made this account in 2007, had not logged on in a long time.]

Made account in 2007, I was of age at this time also, I am 28 years old.  I have already changed it in my prefrences, someone told me via chat that if I added a payment method that this would fix it, I am not sure if they are correct, if they are I will do it, but I want to keep this account. 

[Adult/Age Restricted Content]

Cannot figure out how to access the Adult/Age restricted content, I have changed my prefrences to allow it, I made this account in 2007 I am 28 years old and I am sure I was of age at the time I made the account also.  Any tips ?
