Why can't I make changes to my twitter profile?

[Nasha]

When I try uploading my profile picture it says "Internal Servor Error." And when I try to upload a new header it says "Header Published Succesfully". But when I check to see if my header was uploaded it wasn't. Please help!

Don't know exactly why because I don't have twitter but try these for your profile picture:

1. Check your file type. Twitter supports JPEG, GIFF, and NG file formats. We do not support animated GIFs. All existing animated GIFF images will be left as they are, but no new ones can be uploaded. Profile photos with nudity will be removed.
2. Make sure your file is the correct size. Profile and background photos must be under 2MB; header images must be under 5MB.
3. Make sure your browser is up to date. Try upgrading your browser or using another browser. Your upload problem may be related to the browser or computer you're using.
4. Make sure you click 'Save changes' at the bottom of your Profile settings page. Your image won't save until you click that.

And the header must be 1200x600 in resolution or lower; resize the image if it isn't.
