Fatal error on deactivating plugins check_admin_referer

  • I am trying to deactivate plugins so I can upgrade from 2.0 to 2.0.1, but I get this error:

    Fatal error: Call to undefined function: check_admin_referer() in /pathtodomain/remote.kidsown.ie/wp-admin/plugins.php on line 5

    I dig a bit deeper, and find that I can make posts, but I can’t change options, or switch themes. When I try to switch themes I get this error, roughly the same:

    Fatal error: Call to undefined function: check_admin_referer() in /pathtodomain/remote.kidsown.ie/wp-admin/themes.php on line 5

    What causes this kind of error?

    Without being able to deactivate the plugins, is it safe to attempt an upgrade?
    I am using:
    Audio player 1.0.1 (activated by not using)
    Private Categories 2
    Recent Comments 1.18
    SmileTAG 2.3

    This may be unrelated, but when I tried to download a backup of my site files, it kept on breaking in /wp-content/cache folder (using two different FTP programs) I cannot backup this directory.

    Anyone know what kind of thing causes this “fatal error” the call to an undefined function? I cannot find anything related in the forum here.

    Maybe just some pointers for troubleshooting?

    wow, i promise, i spent ages trying to work this out before i posted!

    but i figured out my fatal error:

    i copied a file from another installation of wordpress, and this caused the problems.

    fixed!
