net::ERR_CONTENT_LENGTH_MISMATCH in Chrome after updating to 5.1.9

[marco_gofem]

When trying to reply to a topic we always get

net::ERR_CONTENT_LENGTH_MISMATCH

The AJAX call in charge seems to try to load ./create-content/loadnewposts

The post gets saved, and after reloading the page it is visible, but loading it via AJAX does not seem to work in Chrome.

Did anyone experience something similar?

We're using Apache with PHP in FastCGI Mode (PHP-FPM) and after we removed the Header('Content-Length') stuff in /includes/vb5/frontend/Controller.php it seems to work in Chrome now..

// sendAsJsonAndCloseConnection Line 295
//Header('Content-Length' ...)
