It is sooo freaking frustrating to have it not allow it

Which bio: the one here in the Support Community, or the one in the main part of Khan Academy?

Hi Tiffanyc,

There's a bug with the "Edit Profile" popup, so if you just changed your bio, you will need to reload the page in order to change it again. Otherwise, the bio field is not shown.

Alternatively, you can always change your bio from the account settings page: https://www.khanacademy.org/settings/account

I hope this helps!

Thanks *Evan Lewis* this helped me.

i had a problem w/changing my bio a few weeks ago, becuz it kept deleting. after some trial and error, if your bio is over the character count (it was either 100 or 160 id remember) it will delete it and restore your OLD bio. try checking how many characters you have.
