I guess the "1" is the line number, which some browsers always show, whether there is content or not. ;-)

A blank page points to a PHP error. Activate error display and check the PHP error log to see what's going on.

You say you use the new PHP 5.4, but an older version of MediaWiki. My guess would be that this version of MediaWiki is just not compatible with PHP 5.4.

A general remark: Your wiki and also your MySQL version are terribly outdated. They have tons of security holes. Maybe you also got hacked. However, even if you did not, with these versions it's only a matter of time. You should really do an Upgrade! Current MediaWiki versions also run fine on PHP 5.4. ;-)
