Hey there. No matter what I do, Every image I upload on the proper site says image type invalid. I tried png and jpg both, taking down the size well under 150x150, even compressed it. Even if I try uploading a portrait, it higlights the "avatar" in red with the same image type invalid massage.

Can you attach that image so that I can check it out?

Well, here are two for example. 1 for avatar, 1 for portrait
(it's completely possible that I'm dumb and overlooking something)
