New version not working

[cluj]

I tried to upgrade to the ne version but it is missing the config.php file so i reinstalled the old version but now i am getting this error:

"Warning: Cannot modify header information - headers already sent by (output started at /home/albumef/public_html/index.php:751) in /home/albumef/public_html/themes/meltingfilm_left/theme.php on line 806

Warning: Cannot modify header information - headers already sent by (output started at /home/albumef/public_html/index.php:751) in /home/albumef/public_html/include/functions.inc.php on line 51"

Can you please help?  my site is www.albumefoto.com  and the error comes at the bottom of the page

Thanks
