How to remove blog post from a deleted user

[GerstnerUSA]

I found 2 blog posts today on my forum that appear to be from deleted users. I found the blog posts when i did a search on my forum.

After trying to view the blog posts, i received the following e-mails.

First Database Error e-mail:

WHERE bloguserid =;

I had someone else from the vbulletin forum that helped setup some mods to eliminate spammers, and they went through and cleaned up my forum, but they might have missed the blog entries.

My question is how do i remove the blog entries since the users have been deleted?

Thank you for your time.
