When a table is added to a forum post and the post is too long, the post becomes truncated. The problem here is that the closing </td>,</tr>,</tbody> and </table> tags are also truncated and therefore the table is not closed. This means that all following content is added to the table including the block on the right. The attached image error1.jpg shows this problem. error2.jpg shows the output in plain text and that the closing tags are removed.
