“Call to undefined function get_admin_page_title” after upgrade

  • I was running WP 2.1 this morning and ran through the upgrade procedure to get to 2.8.4. I extracted the .gz file on my server and moved over the wp-admin and wp-includes folder. I deleted all the files in my root and moved over the settings to the new wp-config.php file. I updated the wp-content folder and I thought I followed all the directions on the site. However, when I go to the wp-admin page it displays “cheatin ‘uh?”. I went directly to my wp-login.php file and was able to login, but as soon as I do, I receive this message:

    Fatal error: Call to undefined function get_admin_page_title() in /home/texarkan/public_html/wp-admin/admin-header.php on line 12

    Any ideas?

    The site seems to be up right now, but I can’t do any admin.

  • you need to re-upload ALL the files insiode the wp-admin/ directory.

    delete EVERYTHING inside it. upload fresh files. Your method of overwriting didnt work, AND its probably left old stray files around as well (which isnt a good idea for a cpl reasons).

    if you have other similar problems, do the same thing for the wp-includes/ directory.

    Originally, I moved the .gz file and extracted it on the server after deleting my original wp-admin and wp-includes folders. After your suggestion, I redownloaded the zip file to my local PC, extracted it, and then uploaded the wp-admin and wp-includes folders via an FTP client. I still have the same error. I have cleaned my cookies and temp files out of my browser but still get the “Call to undefined function get_admin_page_title() in /home/texarkan/public_html/wp-admin/admin-header.php on line 12”

    that function is defined inside wp-admin/includes/plugin.php

    I have renamed the plugin.php file and re-uploaded it with no change in the symptoms.

    I have tried to go to the wp-admin/upgrade.php file and I get a “page cannot be displayed” error. Is this possibly some rights issue? I didn’t change any attributes on any files, but could something be set incorrectly there?

    remove and re-upload all of the core wordpress files.

    including wp-settings.php and all of its friends in the root directory ( minus the wp-config.php, which you should have looked at to make sure all of the new path stuff and whatnot is carried over from the config files)
