Am I the only one?

Yes. I have a similar problem to yours. But, rather than not being able to submit, I need a shorter response.

I've been having that issue (but it also gets rid of my link 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 ubah my profile, I switched back to English fanpop and was able to successfully ubah it right away. Idk, are anda sticking with just regular English Fanpop?

anda have to shorten some of your responses like your favorit buku atau authors atau your favorit film atau song artists. After shortening these, it should allow anda to menyerahkan it. If this still doesn't work, refresh the page a couple of times. I had the exact same thing happen. Hope this helps!
