Target version:Centreon 2.3.9
Resolution:fixed Affect Version:


After i upgraded to 2.3.4, my web gui didn't show hosts and services list and graphs.
I tried some solutions to similar problems i found in the bugs list and forum but they didn't solve the issue.
So i had a look to the php sources and i found in these files centreonGraph.class.php and centreonXMLBGRequest.class.php this piece of code:

if (headers_sent()){
                $encoding = false;
} else if (strpos($HTTP_ACCEPT_ENCODING, 'x-gzip') !== false){
                $encoding = 'x-gzip';
} else if (strpos($HTTP_ACCEPT_ENCODING,'gzip') !== false){
                $encoding = 'gzip';
} else {
                $encoding = false;

in both scripts that causes an Content-encoding: gzip was add in the response to the ajax calls (cause in the request headers it puts Accept-Encoding:gzip,deflate,sdch) even if the script didn't compress the body it sent.
So the javascript received data it couldn't handle (firebug said it got 0 byte data even if in apache logfile i saw the server sent a not null response) and it failed to render the web pages.
I tried to enable the zlib compression in php.in but it solved only the hosts/services issue not the graphics one.
Than i hacked the source code commenting all the if block forcing $encoding to false and that solved my gui problems.
