I can't tell what template that is that you took a screenshot of. I'm guessing that it's in your postbit. If that's the case, you need to review your code in that template.
Another option, although kinda messy with vB, is to validate your code with the W3C [
link]. It's going to give you a lot of errors because of the vB specific code, but it can also help you ferret out where your missing table tag is.
