 * I’m helping a friend with a problem on their blog. They have just started getting
   an error when uploading jpg’s from the upload section on the write post page.
   The images upload, but the send to editor popup does not appear and they have
   to go to “browse all” and then send them to the editor from there. These are 
   the errors being reported, and it has just started in the last day. Earlier uploads
   this week did not have a problem

 * I know bumping threads is considered “bad form” but does anyone have any idea
   what may be causing this?

 * One of the causes of this is a blank line at the beginning of one of the php 
   files. Since we don’t have a url, check your image php and other related to this
   function.
 * You can do a search on cannot modify header information and come up with a lot
   of information.

    Thanks for the
   information. I’ll check the php files and search as you suggested.
