[Mediawiki-l] Blank Page

[Mike Dickson]

When I remove the @ sign, I get the following:

Fatal error: Call to undefined function: mysql_connect() in /var/www/internal/wiki-new/includes/Database.php on line 95

Which I assume means that the mysql bits used by php aren't loading or whatever.  An unfortunate choice of error text suppression.

Thanks to Joshua for the tip on this.

Hi,

I'd rather not as there are several other PHP-Applications on the system
and I know nothing about their requirements.

I have instead added

    ini_set("error_reporting","E_ALL");
    ini_set("display_errors",1);

To MediaWikis index.php. I tried several locations down the file, past
some of the configuration-includes to make sure it does not get unset
again.

No change in the result: Still a 200 http-code but no data.

I then put in a million statements of the form

   echo __FILE__ . __LINE__ . '<br>';

tracing progress through the code the hard way. Passing through lots
of interesting places I finally reached includes/DataBase.php. The
place where the actual connection to the database is attempted in
function open(). I added my echoes and some more dumping-code:

   echo __FILE__ . __LINE__ . '<br>';
   var_dump($server); echo '<br>';
   var_dump($user); echo '<br>';
   var_dump($password); echo '<br>';

   @$this->mConn = mysql_connect( $server, $user, $password );

   echo __FILE__ . __LINE__ . '<br>';

The first echo and the var_dumps are executed. Servername (localhost)
and user and password are looking OK. The last echo does not execute
(or the output does not reach my client).

I have also tried removing the '@' from the mysql_connect-Line. No
change. I don't think I can follow the path of execution any further.

I can connect to the database fine when using the commandline
mysql-client with the servername, username and password that has been
output by my var_dumps. I can select the correct database and
list tables and data.

What now? What could make the system just die without any indication
of a problem?

Ciao, MM
