Upgrading error

[Tiffany]

I  just follow the documenation to do the update of my gallery 1.3.5 to 1.4.4, but after I do the updated, it's just a blank page now   
What I did, was uploading overwriting everything in tne new zip 1.4.4 folder and keep the old config.php,include.php,albums,anycontent.php

Any suggestons are really appreciated.

I read the other topics on about blank page after upgrading, but it didn't help much.
Anway I didnt have that many pictures uploaded yet, so I deleted everything in the old gallery page and doing everything from scratch again. You can close my post now. Thanks
