[Zope] Zope messed up

Hello, At our site, someone installed the Python functions split2 and string in the Zope root. Due to some error, we cannot post anything now: we can't add articles and we cannot use the Zope content management page. We tried removing removing split2 and string. We can remove is from the harddisk, but it's still in the Zope management page. The management functions (rename, delete) still won't work. Please: how can I delete something from the Zope database with defunct Zope management forms?? Thanks, Edwin. --- Surf Edwin Martin's brainwaves: http://www.bitstorm.org/edwin/
