So when I clicked on the "SHOW --> Earned" achievement, it says: "There no unretired achievements in this category, click on 'retired' above to view the achievements in this category."

And when I click on the Retired section, it says the same thing (obviously).

are you using the search function at all, and what browser are you in? firefox will give you problems when searching for things.

When I click on "Newest", "Saved", or "Basic", they don't show up. But under "Basic --> Social", I've earned the "Change your Headshot" achievement. So I'm guessing that it just doesn't show because I haven't earned achievements in that category. I don't really know. D:

No, I'm not using the search function. And the browser I'm using is Chrome.

Okay, the search works fine in chrome so I was just checking :) you should have some show up in newest and basic. it shows you have the Make a Friend achievement when I look under your basic achievements, but looking at other users' achievements doesn't work very well. saved won't have anything in it unless you manually press the check box next to an achievement to save it

Yeah, the "Basic" one works now! I think I just need to earn some achievements for them to show up. :)

glad it works now! it must have been what said :)
