Just installed Avatar Mod for 3.4 and my avatars are showing up as 1x1 pixel gifs. Any idea what I might have screwed up? I have no idea where to begin.
I believe this means that the size isn't showing up in the right place. First, can you check the admin avatar options to make sure that you are selecting the right size from the drop-down menu? If that doesn't work, you probably made a mistake in the code relating to the sizes in the drop-down menu.
I've played around with this code a bit, too, and have seen the 1x1 pixel GIFs you're talking about.
