open ./inc/config.php file in a code editor like notepad++
ensure that there are no spaces or characters before <?php and after ?>
save the file as utf-8 file without BOM
Are you using any plugins? If so, please list them.
If you are not, the next step is to use the file verification tool. ACP->Tools->File Verification. Ignore any images and anything in the /install directory.

What was ok? Show the file here (with erased sensitive data, of course).
It's not ok.. There are multiple whitespaces before <?php and after ?>, remove them.
