Okay, I have a small problem here. I was going to upload new avatar for myself, but each and every time I try to save the changes I get error "Invalid File". I tried several different versions of the same image, each of them being at most 14kb in size and at max 75*75 pixels, so neither cap was crossed. I have tried several different file types, GIF, JPG, PNG and even BMP, with no luck. I checked all the FAQ sections as well as used Search feature to see if I was missing something vital, but there is no other restrictions mentioned besides the kb and pixel limits. The problem also exists if I try to use picture uploaded elsewhere, like Photobucket. For the record I tried to change to another preset avatar, and that worked flawlessly. Any ideas?
