Error preventing me from accessing my site..

Delete the plugin manually. Go in via FTP and delete yet-another-multi-site-manager

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?

NOT the same issue, and you need to do a manual upgrade. If that doesn’t help, make a separate topic.

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

Anes101 – Bear in mind it’s rude to jump in on an unrelated post with your problem. It’s like being Kanye when Taylor Swift won the Grammy. Keep to your topic.

Tooler, let us know how it goes!

Good day: I have problems logging into my account receive the following message:

“PHP 5.1 or later Requires: no simplexml_load_file ()
Warning: Can not modify header information – headers already sent by (output started at / home/tn000015/public_html/wp-content/plugins/twitter/widget_twitter_vjck.php: 73) in / home/tn000015/public_html/wp-includes/pluggable. php on line 897

I can do?

I hope to answer. Thanks

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