   Hi,
   After upgrading to 2.0 I had memory issues and could not get to my admin panel. So I increased the memory limit to 64M and all seemed to be fine the 2 times I logged into my admin panel yesterday.

   Now I'm getting this after trying to go the admin panel.

   I get the following after logging in from the login page (if i go to the login page via direct address)

   Warning: Cannot modify header information - headers already sent by (output started at /home/politii4/public_html/wp-config.php:153) in /home/politii4/public_html/wp-login.php on line 287

   If I download the 2.8 zip file, then load it into my site FTP, will that not erase my site? (overight all of my settings, plugins, posts etc)

   This seems to be the line that comes up

   Before any manual or auto upgrade BACKUP DATABASE, Files/Folders. Also, it would better if you check your plugins compatibility first because that could cause problems in the upgrade. If your plugins are A MUST in your install, maybe it would be better to hold off upgrading till the plugins you need have been updated as well.

   Right.
   I already upgraded which is why I'm having this problem.

   I guess I am just going to have to join the masses and do a manual downgrade.

   Any suggestions on fixing this error?

   I had the same issue. It ended up being the "Bad Behavior" plugin. Don't know if it was that solely but when i took it off, the problem went away.
