Thread:Project:Support desk/Error 500 instead of email

Dear supporters,

when trying to send an email from the wiki, I get:

Server Error 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed. (and nothing else).

in LocalSettings.php, I included: $wgDebugToolbar = true; $wgShowDebug = true; $wgDebugComments = true; $wgShowExceptionDetails = true; $wgDBerrorLog = "/tmp/logs-mediawiki-dberror.log"; $wgRateLimitLog = "/tmp/logs-mediawiki-ratelimit.log"; $wgDebugLogFile = "/tmp/logs-mediawiki_{$wgDBname}.log"; $wgDebugLogGroups = array(     'BMWExtension'      => "/tmp/logs-mediawiki-BMWExtension.log",     'LpvDebug'          => "/tmp/logs-mediawiki-LpvDebug.log",     'resourceloader'    => "/tmp/logs-mediawiki-resourceloader.log",     'exception'         => "/tmp/logs-mediawiki-exception.log",     'error'             => "/tmp/logs-mediawiki-error.log",     'exception-json'    => "/tmp/logs-mediawiki-exception.json", ); and $wgSMTP = array(  'host'     => "172.168.1.3",               // could also be an IP address. Where the SMTP server is located   'IDHost'   => "my-domain.vn",              // Generally this will be the domain name of your website (aka  mywiki.org)   'port'     => 25,                          // Port to use when connecting to the SMTP server   'auth'     => true,                        // Should we use SMTP authentication (true or false)   'username' => "wiki-daemon@my-domain.vn",  // Username to use for SMTP authentication (if being used)   'password' => "wikimailer"                 // Password to use for SMTP authentication (if being used) );

$wgEnableEmail = true ; $wgEmailAuthentication = true;

$wgRequirePasswordforEmailChange = true;
 * 1) $wgEmailConfirmToEdit = true;

Some logfiles exist, but they all are old. Nothing is from the try to send email.

Versions:
 * Windows 7 Server
 * MediaWiki 1.24.1
 * PHP 5.6.5 (cgi-fcgi)
 * MySQL 5.6.21-log

Thanks in advance for your support. Son
