can't change avatar on forums

so I tried uploading a new picture, it goes, but when I click save changes, it reverts, if I delete the picture etc same deal, anyone else having this issue?

I've tried removing the avatar I uploaded, I've tried uploading from url, but soon as I click save changes to profile it reverts, I evern tried another browser

There's a delay when you change your avatar, likely due to either the forum scripts or your browser having to recache your avatar.

yeah it seems to be something to do with cache, but you'd think the site for force the browser to update on such a change, thanks anyways. EDIT: on chrome if you press crtl F5 it forces the cache to reload for that website, this fixed my issue
