Failure To Change Forum Avatar
I tried searching for another thread but couldn't find one about this; as such I am sorry if I make a duplicate thread.
I am having trouble changing my avatar on the forums, every time I change it, it shows a broken image. I've tried uploading various versions of the image I want:
Default Size 750x750 png
I'm honestly not sure whats happening if someone could help me out? I've also tried clearing my browser cache to make sure that it wasn't causing a problem. Thank you for anyone who helps!
