Strange message errors

[Naif]

Hello everybody

My galery has suddenly begun to show these error messages on the top of the page:

Notice: Undefined variable: HTTP_POST_VARS in /home/.cutie/naif/theothersize.com/galeria/include/init.inc.php on line 160

Notice: Undefined variable: HTTP_GET_VARS in /home/.cutie/naif/theothersize.com/galeria/include/init.inc.php on line 168

Notice: Undefined variable: HTTP_COOKIE_VARS in /home/.cutie/naif/theothersize.com/galeria/include/init.inc.php on line 187

Notice: Undefined variable: HTTP_SERVER_VARS in /home/.cutie/naif/theothersize.com/galeria/include/init.inc.php on line 195

Notice: Undefined variable: HTTP_SERVER_VARS in /home/.cutie/naif/theothersize.com/galeria/include/init.inc.php on line 202

And it's actually unaccessible at all. There is no way to click on the links, view the pages or even login. What could be happening?

Update your gallery. 1.3 is no longer supported.

I have tried to do so, but now the error message is: "Fatal error".

If you have upgraded, you should post on the board that corresponds to your new version. Locking.
