Archive.php empty response error

Hello everyone,

I am trying to use Matomo auto archiving but it doesn’t work and here is the error:

Error: Empty or invalid response '#!/usr/bin/env php Warning: session_cache_limiter(): Cannot change cache limiter when headers already sent in /home/www/public_html/analytics/core/bootstrap.php on line 32 ' for website id

And here is the php error_log:

[26-Dec-2018 20:17:11 UTC] PHP Warning: session_cache_limiter(): Cannot change cache limiter when headers already sent in /home/www/public_html/analytics/core/bootstrap.php on line 32

I am using php 7.3, and the latest V of Matomo is installed.

I’ve already tried setting timezone and blah blah blah with no success!

Any idea?

Same here… Any suggestions would be appreciated… Tested in Matomo 3.8.1 and 3.9.1, PHP 7.2 and PHP 7.3
