Have you ticked NSFW in your Settings page?

yes, and i can see the pics on my mobile phone. but still not on my browser. (i use google chrome and i already tested it with internet explorer)

Does you bar look like this when you search walls?

it looks exactly like that.

no, wait. the nsfw button is not marked red. but when i press the buttton, there appears a circle and nothing more happens. the circle lasts there until i press escape.

Mark NSFW and press the refresh button to your right. (also shown in the screenshot of AbstractART)

when i press the refresh button, i am asked if i'm over 18, then i click on the yes button and nothing happens. When i press the no button, i will return to the main page.

could be an issue with your browser.. do you still have another one installed(Internet Explorer, Firefox, or other browser)?

Don't suggest Internet explorer you little bastard, try chrome or firefox.

well, I had to suggest something, and we both could' ve read his posts better,
already tried chrome and IE, but both didn't work.. :)
except clearing the cache, and offline website data(and some other junk too), i can suggest a diffirent computer,

clearing the cache, delete offline website data and other junk, just hit ctrl - shift - delete all at the same time.

I have cleared the Cache of both browsers and now it's working! Thank you very much. :)
