installation error : Warning: ob_start() ...

Question

I just installed question2answer script in my hosting, I got the following error on top of my installation ; http://www.herkesuzman.com/q2a

Warning: ob_start() [ref.outcontrol]: output handler 'ob_gzhandler' conflicts with 'zlib output compression' in /home/polo6r/public_html/q2a/qa-include/qa-index.php on line 149

Does anyone knows why this error occurs?

Answer 1

It sounds like your web server is already compressing content, so Q2A's attempt to do the same is clashing. You can fix this by modifying this line in qa-config.php:

define('QA_HTML_COMPRESSION', true);

... to ...

define('QA_HTML_COMPRESSION', false);

I tried your proposition but it gave me this error this time ;


Warning: Cannot modify header information - headers already sent by (output started at /home/polo6r/public_html/q2a/qa-include/qa-util-string.php:1) in /home/polo6r/public_html/q2a/qa-include/qa-page.php on line 684

Yes, that's a different issue - qa-util-string.php has a UTF-8 BOM character at the start - you should hopefully be able to remove this with a text editor.

which text should I try to remove in qa-util-string.php?
There are many codes including UTF-8 inside...
