That happens when you try to change your avatar to something.
Both images are around 1000 X 700
I made an image that is 160 X 26
1; same result.
I have to
take photoshop and the image I want to use as an avatar and make the image 160 X 260.
Clearing my cookies did not fix this.
Another bug: When you post a reply on a thread, delete the reply you just did, and try to post again, it is just so jacked up.
After you delete a post and try to post again (on the same thread), it first thinks you're trying to edit the post you just deleted,
and then it thinks your just posting (which is does not post what you type),
and THEN the third time it thinks you're trying to edit the post, but it is actually posting the reply inside the post editor.
Sometimes it allows me to post after the second try, and sometimes it allows me to post on the third try.
