I've been having that issue (but it also gets rid of my 链接 when I update it that way). I'm getting fed up with it. I'm not sure if this is coincidence, but after a long time of trying to 编辑 my profile, I switched back to English 潮流粉丝俱乐部 and was able to successfully 编辑 it right away. Idk, are 你 sticking with just regular English Fanpop?
你 have to shorten some of your responses like your 最喜爱的 图书 或者 authors 或者 your 最喜爱的 电影院 或者 song artists. After shortening these, it should allow 你 to 提交 it. If this still doesn't work, refresh the page a couple of times. I had the exact same thing happen. Hope this helps!
