If I click any module these are my list of errors:

Warning [PHP]: session_start(): Cannot send session cookie - headers already sent by (output started at D:\hshome\stevenso\futureamerica.us\index.php:1) in file D:\hshome\stevenso\futureamerica.us\include\common.php line 177
Warning [PHP]: session_start(): Cannot send session cache limiter - headers already sent (output started at D:\hshome\stevenso\futureamerica.us\index.php:1) in file D:\hshome\stevenso\futureamerica.us\include\common.php line 177

Warning [PHP]: Cannot modify header information - headers already sent by (output started at D:\hshome\stevenso\futureamerica.us\index.php:1) in file D:\hshome\stevenso\futureamerica.us\index.php line 42

I've searched around for the cause and found one link that said having space after the ?> caused these errors. I fixed a couple of these spacing problems in my files but it didn't help. I also found one link that indicated it could be with the server.

I was able to select a module for my start page when I first installed XOOPS and then at some point I couldn't.

Please help!
