Webinstall.php error... now forum won't work. Help? :(

[Jorge D. Fuentes]

I was running 1.1.14 with mods.
Tried to upgrade to 2.0 using the webinstall.php file.

I placed the file in the right FTP directory, then ran the installer.  After I get to about 87% or so on the red bar, this error comes up:
"Warning: Cannot modify header information - headers already sent by (output started at /home/cvdungeon/www/castlevaniadungeon.net/forums/webinstall.php:2) in /home/cvdungeon/www/castlevaniadungeon.net/forums/webinstall.php on line 916"

And now my forum won't work.
I'd appreciate any help.

Also I have a backup of the forum from yesterday.  If I messed up, how do you restore?  Any help would be appreciated.
**is worried**

if the webinstall does not work you can use the normal upgrade methods Upgrading SMF
