Hi Ipstenu, I’m back just to say that I have successfully upgraded manually by re-overwrite the wp-include folder.
.
Thanks and Regards

Hi t-p, I’m happy to say that I have successfully upgraded manually.
I noticed that the wp-include folder is the cause, even though previously I made sure everything looks like okay. With the override again it worked well.
Thanks for the help that has provided guidance on this issue.
Greeting.

Yes, I’ve made a separate topic in WordPress ? Support ? Installation

I did a manual upgrade but have not succeeded and the message:
Fatal error: Call to undefined method WP_Rewrite:: add_rewrite_tag () in / home/us54t31l/public_html/wp-includes/taxonomy.php on line 331

I had to fight to fix this, all suggestions and help I really appreciate.

Thanks

Oh my God, I can spend my week for this one.
Thank you t-p, I’ll do it until it works.

Thanks for the response.
After disabling plugins, switch to the twentyten theme still a problem, I replace the new copy of WordPress as instructed above manually. After following these steps and try to login to wp admin and access the site, the same error message appears: Fatal error: Call to undefined method WP_Rewrite:: add_rewrite_tag () in / home/us54t31l/public_html/wp-includes/taxonomy.php on line 331
I do not know where the error occurred and what should I do now?

Geez, I have encountered the same problem. My site uses dirty-blue theme.
I was just automatically upgraded from version 3.0.1 to version 3.1 and after urgrade declared a success, I can not go back to the dashboard and show the message: Fatal error: Call to undefined function get_option () in / home/us54t31l/public_html/wp-admin / admin.php on line 32
I have check admin.php line 32 but I do not know what to do, as follows:
32 if ( get_option(‘db_upgraded’) ) {
33 $wp_rewrite->flush_rules();
34 update_option( ‘db_upgraded’, false );

Is there anyone who can help?
