In vault/core/controller/progress/vw.php, find:

Code:

header('Cache-Control: no-cache');

Remove it.
Then find:

Code:

ob_implicit_flush(true);

Add after:

Code:

header('Cache-Control: no-cache');

That should resolve this particular error here, although I don't know what output would have already been started before getting here. The output it's not showing is probably an error.

I have the same problem. It appears that the new version of VaultWiki has made this change but I'm still stuck at 1%. Hitting manual mode I get the following.

set_time_limit() has been disabled for security reasons

Enabling it in php.ini worked. I'm guessing this is a problem to many who are on shared hosting.

Added the @ operator everywhere set_time_limit() is used in the next release.
