ok well i've had my avatar now for like 6 months now and on firday it just didn't appear on my posts. i didn't think much of it and when i went to go put it back on it wont allow me to. the avatar is 125x125 and is 21.7 KB. it just wont let me use that avatar. it allows me to use differnt avatars but not this one. is there any way to fix it?
