    After upgrading to 3.9 I get the following error message if I try to change the theme:

    Fatal error: Call to undefined function current_action() in D:\XXXX\yyyyy\blog\wp-includes\theme.php on line 758

    I also get following error message when I try to activate the Akismet or WordPress SEO Yoast plugins:

    Fatal error: Call to undefined function wp_register_plugin_realpath() in D:\XXXX\yyyyy\blog\wp-admin\plugins.php on line 150

    How can I solve this?
    Thanks,
    Dirk

    Try re-uploading all files & folders – except the root wp-config.php & .htaccess files and the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    I can confirm that esmi’s advice helped in my situation except you should not have to delete any folders or files. Just replace any existing wordpress files from a fresh installation. The latest.zip and latest.tar.gz files do not contain the wp-config.php and .htaccess file anyways so unzipping/untarring them directly to your current wordpress installation (replacing exiting files) should be safe but always backup your wordpress installation (both files and DB) before performing this process.

    Extensive experience suggests that over-writing may not be enough in some cases. Which is why we specifically recommend that you delete the old copies of files & folder before uploading the new ones. Please stop posting poor advice about this.
