UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? adding new gremlins

Is that the message you got from the update/delete icons button?

If so, then you may need to ftp into your hosting space and manually remove the graemlin.


EDIT:
Alternatively - you could try to ftp to the graemlin and give it 777 permissions; then maybe UBB could remove it cleanly.
