MediaWiki Installation
In order to configure the wiki you have to make the config subdirectory
writable by the web server. Once configuration is done you'll move the created
LocalSettings.php to the parent directory, and for added safety you can
then remove the config subdirectory entirely.
To make the directory writable on a Unix/Linux system:
Warning:PHP's register_globals option is enabled. Disable it if you can.
MediaWiki will work, but your server is more exposed to PHP-based security vulnerabilities.
Fatal: magic_quotes_runtime is active!
This option corrupts data input unpredictably; you cannot install or use
MediaWiki unless this option is disabled.
Fatal: magic_quotes_sybase is active!
This option corrupts data input unpredictably; you cannot install or use
MediaWiki unless this option is disabled.
Fatal: mbstring.func_overload is active!
This option causes errors and may corrupt data unpredictably;
you cannot install or use MediaWiki unless this option is disabled.
Fatal: zend.ze1_compatibility_mode is active!
This option causes horrible bugs with MediaWiki; you cannot install or use
MediaWiki unless this option is disabled.
