I am in the process of upgrading to 6.2.1 from 5.47a and am at the step where I am running 'Rebuild Search Index'. the problem I am having is that twice already I am getting an error about 'zero-sized topic' and the rebuild ends. I have deleted those specific .cgi files from my forum, but then have to start all over.

Is there a way for ubb to find and delete these zero sized topics?
