nearly the same error
Fatal error: Call to undefined function: force_ssl_admin() in /www/htdocs/w007ee2d/ferndesign/wordpress/wp-settings.php on line 390
upgrade from wp 2.5.1 to wp 2.6 – manual upgrade with ftp
domain: http://www.ferndesign.biz
(error isn’t visible on my page anymore – restored a backup..)
I contacted my host who fixed whatever the problem was – they didn’t say. Though now i’m having the blank screen issue.
“Call to undefined function” almost always means that you didn’t upgrade every single file.
Re-upload WordPress, and this time, upload ALL the files. Even those in the root directory.
I just had this problem, for some reason some files didn’t upload properly – these things happen.
I have a lot of clients, and I use WordPress for almost all of them. Here’s how I systematically upgrade multiple sites:
1) Build a special zip file with the new version of WordPress. I delete the wp-content folder and the wp-config-sample.php. I may leave the wp-content folder if I want to upload a set of new plugins that I intend to use, but delete the theme folder.
2) On the host – delete all folders and files with the exception of wp-content folder, wp-config.php, and .htaccess (if you’re running WP from the root folder).
3) Upload the ZIP file to your host, unpack everything.
4) Ta-da.
