Was the insights BB-Code inside a TABLE? When I asked for sample code, I was looking for an overall context that would show me how it would interact with other BB-Codes.
For example, if you were using vBulletin TABLE syntax, with line breaks between TR or TD, but VaultWiki TABLE was actually set-up to parse instead, then the contents of the table would be pushed down because TR/TD don't mean anything to VaultWiki's BB-Code, so the line breaks are expected to be intended literally.
This is just one example, but that's why it's important to send the full source code when BB-Code isn't looking right.
