You already have a post regarding this, the error is the same. Check what I replied:

Hello,

Some function (plugin, functions.php...) is outputting data at the start of the PHP script which prevents redirecting and such stuff.
Disable all plugins one by one and look for some "fishy" code in functions.php, it looks like there's a code like this somewhere: "var_dump(Params::printParamsAsArray());".

Regards.

Regards.
