Hi Dennis,

Have you 'grep'ed for the field name in the lib, perl_lib and archive/ARCHIVE_ID/cfg directories to see where it might still be defined?

    Hi David,

    Thanks for the reply!

    It's a custom field on the eprint data object. I already removed the
    subfield from all of the mentioned files. Is field information also
    stored or cached elsewhere? I saw some references in mf* tables, but
    removing those also didn't work.
