Avatar problem

Hello, I'm a new user to this forum and I am experiencing a slightly small problem regarding my avatar. Whenever I tried to place the URL, it always say invalid URL. This is probably not a problem on my side as I tried to change the URL, or even its origin and yet, I still get the same problem. Please do look in this matter if possible.

Try changing your avatar now, and then tell me what happens .

Well, I attempted at changing my avatar but it was in vain. It kept on repeating that the URL was invalid even if it was from gravatar. T^T
I'm sorry if this is too much of a hassle. T^T
