Upgrading Drupal

I have a problem upgrading to drupal 4.7. beta 4.
Currently we are using 4.6.0. I tried upgrading directly to 4.7. and I tried by passing through 4.6.5. but both give me the same message when running update.php.
upgrade 4.6.0 to 4.6.5. + update.php works well but upgrade from 4.6.5. to 4.7. is not ok:

After running update.php I get following error message:

Hi, I'm new in using drupal and it is so cOoL.but i have a problem i can't solve it with on line support in drupal .
i make a page which recive variables from another in post method and i wanna to write these vars in a file ,when i creat the page and send the vars to it these warning appeare and it doesn't work and there is no action made by the page in the file and the file still blank. the warning as follow:

CALLING ACIDFREE I hAVE THIS MESSAGE ERROR

hey all-

Finally finished an upgrade from 4.5.2 to 4.6.5.
I didn't have many add on module, except one in particular, and that was inline. (I believe)No upgrade of the module was needed with a mv to 4.6.x, but when I reinstalled the module I got this error:

warning: filesize(): Stat failed for files/vc52boy.jpg (errno=2 - No such file or directory) in /home/shojo/public_html/test_site/modules/inline/inline.module on line 111.

and

I've been playing with updating BlogTheme to work with 4.7 (http://addingunderstanding.com/blogtheme_module_drupal_4.7). The oddity is that with the module (blog_theme.module) in the /modules/ directory it works fine. Moving the same file to /modules/blogtheme or /modules/blog_theme and it is no longer called at all.

Is this a bug or something I did wrong with the module?
