I had this prob too guys to solve this prob. you have to edit one file.
edit File: -
/arcade/funtions/functions.php

Find

$check = getimagesize($member_avatar);
			$avatarwidth  = $check[0];
			$avatarheight = $check[1];

And Delete these codes

Find

<img src='{$member_avatar}' border='0' alt='' width='{$avatarwidth}' height='{$avatarheight}' />

and Change {$avatarheight} with the Height of avater you want same with Width.

Eg.

<img src='{$member_avatar}' border='0' alt='' width='120' height='120' />

I Hope i didn't made mistake And enjoy.
