I have phpbb 3.0.0 with phpBB3 SEO Advanced mod Rewrite 0.4.0 .

I try to upgrade phpbb 3.0.0 to 3.0.4 with auto update package ( http://www.phpbb.com/files/archive/upda ... _to_3.0.4/ )

But I get this error.

Fatal error: Call to a member function url_rewrite() on a non-object in /home/erkin/public_html/forum/includes/functions.php on line 1741

What should I do?

Oh, but these are quite old versions.
What you could to circumvent this error would be to remove the phpBB edits in includes/functions.php, in the append_sid() function.

Though, Since you have so many version to update, you should probably go for a frontal merge against the latest version directly. You could even take this occasion to go for the premod (the article explains more about the frontal merge method).
