Delete temporary files?

[Ernst Bammer]

Hi,
I've done something stupid: I've deleted some comments from the
database (from the table ROLLER_COMMENT). But they still show up in
the admin interface and on the site. But I can't delete them in the
admin interface because they are not really there anymore (in the
database).
Tried to delete cache and restarted, but did not help.
Any suggestions?
Thanks.
Ernst
