Help!

I upgraded to the new version of wordpress and get this error when trying to access my control panel.


Warning: Cannot modify header information - headers already sent by (output started at /home/jhyjek/public_html/random-thoughts-blog/wp-includes/functions.php:1785) in /home/jhyjek/public_html/random-thoughts-blog/wp-includes/pluggable.php on line 689

Here's the script. Can anyone help?? The script is too long to ad the whole thing here, so I hope I copied enough.

Thanks,

Check your php.ini for output_buffering

http://us3.php.net/ref.outcontrol


Toggle it on/off and test each.

 

thanks for the reply...but I don't know anything about PHP at all. Can anyone post the correction that I need to make?
